Members| Member name | Value | Description | |
|---|---|---|---|
| Undefined | 0 | Undefined | |
| Ok | 1 | No error. | |
| IoPending | -1 | An asynchronous IO operation is not yet complete. This usually does not indicate a fatal error. Typically this error will be generated as a notification to wait for some external notification that the IO operation finally completed. | |
| Failed | -2 | A generic failure occurred. | |
| Aborted | -3 | An operation was aborted ( due to user action). | |
| InvalidArgument | -4 | An argument to the function is incorrect. | |
| InvalidHandle | -5 | The handle or file descriptor is invalid. | |
| FileNotFound | -6 | The file or directory cannot be found. | |
| TimedOut | -7 | An operation timed out. | |
| FileTooBig | -8 | The file is too large. | |
| Unexpected | -9 | An unexpected error. This may be caused by a programming mistake or an invalid assumption. | |
| AccessDenied | -10 | Permission to access a resource, other than the network, was denied. | |
| NotImplemented | -11 | The operation failed because of unimplemented functionality. | |
| InsufficientResources | -12 | There were not enough resources to complete the operation. | |
| OutOfMemory | -13 | Memory allocation failed. | |
| UploadFileChanged | -14 | The file upload failed because the file's modification time was different from the expectation. | |
| SocketNotConnected | -15 | The socket is not connected. | |
| FileExists | -16 | The file already exists. | |
| FilePathTooLong | -17 | The path or file name is too long. | |
| FileNoSpace | -18 | Not enough room left on the disk. | |
| FileVirusInfected | -19 | The file has a virus. | |
| BlockedByClient | -20 | The client chose to block the request. | |
| NetworkChanged | -21 | The network changed. | |
| BlockedByAdministrator | -22 | The request was blocked by the URL blacklist configured by the domain administrator. | |
| SocketIsConnected | -23 | The socket is already connected. | |
| ConnectionClosed | -100 | A connection was closed = corresponding to a TCP FIN. | |
| ConnectionReset | -101 | A connection was reset = corresponding to a TCP RST. | |
| ConnectionRefused | -102 | A connection attempt was refused. | |
| ConnectionAborted | -103 | A connection timed out as a result of not receiving an ACK for data sent. This can include a FIN packet that did not get ACK'd. | |
| ConnectionFailed | -104 | A connection attempt failed. | |
| NameNotResolved | -105 | The host name could not be resolved. | |
| InternetDisconnected | -106 | The Internet connection has been lost. | |
| SslProtocolError | -107 | An SSL protocol error occurred. | |
| AddressInvalid | -108 | The IP address or port number is invalid = e.g., cannot connect to the IP address 0 or the port 0. | |
| AddressUnreachable | -109 | The IP address is unreachable. This usually means that there is no route to the specified host or network. | |
| SslClientAuthCertNeeded | -110 | The server requested a client certificate for SSL client authentication. | |
| TunnelConnectionFailed | -111 | A tunnel connection through the proxy could not be established. | |
| NoSslVersionsEnabled | -112 | No SSL protocol versions are enabled. | |
| SslVersionOrCipherMismatch | -113 | The client and server don't support a common SSL protocol version or cipher suite. | |
| SslRenegotiationRequested | -114 | The server requested a renegotiation = rehandshake,. | |
| ProxyAuthUnsupported | -115 | The proxy requested authentication = for tunnel establishment, with an unsupported method. | |
| CertErrorInSslRenegotiation | -116 | During SSL renegotiation = rehandshake,, the server sent a certificate with an error. Note: this error is not in the -2xx range so that it won't be handled as a certificate error. | |
| BadSslClientAuthCert | -117 | The SSL handshake failed because of a bad or missing client certificate. | |
| ConnectionTimedOut | -118 | A connection attempt timed out. | |
| HostResolverQueueTooLarge | -119 | There are too many pending DNS resolves, so a request in the queue was aborted. | |
| SocksConnectionFailed | -120 | Failed establishing a connection to the SOCKS proxy server for a target host. | |
| SocksConnectionHostUnreachable | -121 | The SOCKS proxy server failed establishing connection to the target host because that host is unreachable. | |

| SslNoRenegotiation | -123 | The peer sent an SSL no_renegotiation alert message. | |
| WinsockUnexpectedWrittenBytes | -124 | Winsock sometimes reports more data written than passed. This is probably due to a broken LSP. | |
| SslDecompressionFailureAlert | -125 | An SSL peer sent us a fatal decompression_failure alert. This typically occurs when a peer selects DEFLATE compression in the mistaken belief that it supports it. | |
| SslBadRecordMacAlert | -126 | An SSL peer sent us a fatal bad_record_mac alert. This has been observed from servers with buggy DEFLATE support. | |
| ProxyAuthRequested | -127 | The proxy requested authentication = for tunnel establishment. | |
| SslUnsafeNegotiation | -128 | A known TLS strict server didn't offer the renegotiation extension. | |
| SslWeakServerEphemeralDhKey | -129 | The SSL server attempted to use a weak ephemeral Diffie-Hellman key. | |
| ProxyConnectionFailed | -130 | Could not create a connection to the proxy server. An error occurred either in resolving its name, or in connecting a socket to it. Note that this does NOT include failures during the actual "CONNECT" method of an HTTP proxy. | |
| MandatoryProxyConfigurationFailed | -131 | A mandatory proxy configuration could not be used. Currently this means that a mandatory PAC script could not be fetched, parsed or executed. | |
| PreconnectMaxSocketLimit | -133 | We've hit the max socket limit for the socket pool while preconnecting. We don't bother trying to preconnect more sockets. | |
| SslClientAuthPrivateKeyAccessDenied | -134 | The permission to use the SSL client certificate's private key was denied. | |
| SslClientAuthCertNoPrivateKey | -135 | The SSL client certificate has no private key. | |
| ProxyCertificateInvalid | -136 | The certificate presented by the HTTPS Proxy was invalid. | |
| NameResolutionFailed | -137 | An error occurred when trying to do a name resolution = DNS,. | |
| NetworkAccessDenied | -138 | Permission to access the network was denied. This is used to distinguish errors that were most likely caused by a firewall from other access denied errors. See also ERR_ACCESS_DENIED. | |
| TemporarilyThrottled | -139 | The request throttler module cancelled this request to avoid DDOS. | |
| HttpsProxyTunnelResponse | -140 | A request to create an SSL tunnel connection through the HTTPS proxy received a non-200 = OK, and non-407 = Proxy Auth, response. The response body might include a description of why the request failed. | |
| SslClientAuthSignatureFailed | -141 | We were unable to sign the CertificateVerify data of an SSL client auth handshake with the client certificate's private key. Possible causes for this include the user implicitly or explicitly denying access to the private key, the private key may not be valid for signing, the key may be relying on a cached handle which is no longer valid, or the CSP won't allow arbitrary data to be signed. | |
| MsgTooBig | -142 | The message was too large for the transport. = for example a UDP message which exceeds size threshold,. | |
| SpdySessionAlreadyExists | -143 | A SPDY session already exists, and should be used instead of this connection. | |
| WsProtocolError | -145 | Websocket protocol error. Indicates that we are terminating the connection due to a malformed frame or other protocol violation. | |
| ProtocolSwitched | -146 | Connection was aborted for switching to another protocol. WebSocket abort SocketStream connection when alternate protocol is found. | |
| AddressInUse | -147 | Returned when attempting to bind an address that is already in use. | |
| SslHandshakeNotCompleted | -148 | An operation failed because the SSL handshake has not completed. | |
| SslBadPeerPublicKey | -149 | SSL peer's public key is invalid. | |
| SslPinnedKeyNotInCertChain | -150 | The certificate didn't match the built-in public key pins for the host name. The pins are set in net/http/transport_security_state.cc and require that one of a set of public keys exist on the path from the leaf to the root. | |
| ClientAuthCertTypeUnsupported | -151 | Server request for client certificate did not contain any types we support. | |
| OriginBoundCertGenerationTypeMismatch | -152 | Server requested one type of cert, then requested a different type while the first was still being generated. | |
| CertCommonNameInvalid | -200 | The server responded with a certificate whose common name did not match the host name. This could mean: 1. An attacker has redirected our traffic to his server and is presenting a certificate for which he knows the private key. 2. The server is misconfigured and responding with the wrong cert. 3. The user is on a wireless network and is being redirected to the network's login page. 4. The OS has used a DNS search suffix and the server doesn't have a certificate for the abbreviated name in the address bar. | |
| CertDateInvalid | -201 | The server responded with a certificate that, by our clock, appears to either not yet be valid or to have expired. This could mean: 1. An attacker is presenting an old certificate for which he has managed to obtain the private key. 2. The server is misconfigured and is not presenting a valid cert. 3. Our clock is wrong. | |
| CertAuthorityInvalid | -202 | The server responded with a certificate that is signed by an authority we don't trust. The could mean: 1. An attacker has substituted the real certificate for a cert that contains his public key and is signed by his cousin. 2. The server operator has a legitimate certificate from a CA we don't know about, but should trust. 3. The server is presenting a self-signed certificate, providing no defense against active attackers = but foiling passive attackers. | |
| CertContainsErrors | -203 | The server responded with a certificate that contains errors. This error is not recoverable. MSDN describes this error as follows: "The SSL certificate contains errors." NOTE: It's unclear how this differs from ERR_CERT_INVALID. For consistency, use that code instead of this one from now on. | |
| CertNoRevocationMechanism | -204 | The certificate has no mechanism for determining if it is revoked. In effect, this certificate cannot be revoked. | |
| CertUnableToCheckRevocation | -205 | Revocation information for the security certificate for this site is not available. This could mean: 1. An attacker has compromised the private key in the certificate and is blocking our attempt to find out that the cert was revoked. 2. The certificate is unrevoked, but the revocation server is busy or unavailable. | |
| CertRevoked | -206 | The server responded with a certificate has been revoked. We have the capability to ignore this error, but it is probably not the thing to do. | |
| CertInvalid | -207 | The server responded with a certificate that is invalid. This error is not recoverable. MSDN describes this error as follows: "The SSL certificate is invalid." | |
| CertWeakSignatureAlgorithm | -208 | The server responded with a certificate that is signed using a weak signature algorithm. | |
| CertNonUniqueName | -210 | The host name specified in the certificate is not unique. | |
| CertWeakKey | -211 | The server responded with a certificate that contains a weak key = e.g. a too-small RSA key. | |

| InvalidUrl | -300 | The URL is invalid. | |
| DisallowedUrlScheme | -301 | The scheme of the URL is disallowed. | |
| UnknownUrlScheme | -302 | The scheme of the URL is unknown. | |
| TooManyRedirects | -310 | Attempting to load an URL resulted in too many redirects. | |
| UnsafeRedirect | -311 | Attempting to load an URL resulted in an unsafe redirect = e.g., a redirect to file:// is considered unsafe. | |
| UnsafePort | -312 | Attempting to load an URL with an unsafe port number. These are port numbers that correspond to services, which are not robust to spurious input that may be constructed as a result of an allowed web construct = e.g., HTTP looks a lot like SMTP, so form submission to port 25 is denied,. | |
| InvalidResponse | -320 | The server's response was invalid. | |
| InvalidChunkedEncoding | -321 | Error in chunked transfer encoding. | |
| MethodNotSupported | -322 | The server did not support the request method. | |

| ResponseHeadersTooBig | -325 | The headers section of the response is too large. | |
| PacStatusNotOk | -326 | The PAC requested by HTTP did not have a valid status code = non-200. | |
| PacScriptFailed | -327 | The evaluation of the PAC script failed. | |
| RequestRangeNotSatisfiable | -328 | The response was 416 = Requested range not satisfiable, and the server cannot satisfy the range requested. | |
| MalformedIdentity | -329 | The identity used for authentication is invalid. | |

| UnsupportedAuthScheme | -339 | An HTTP Authentication scheme was tried which is not supported on this machine. | |
| EncodingDetectionFailed | -340 | Detecting the encoding of the response failed. | |
| MissingAuthCredentials | -341 | = GSSAPI, No Kerberos credentials were available during HTTP Authentication. | |
| UnexpectedSecurityLibraryStatus | -342 | An unexpected, but documented, SSPI or GSSAPI status code was returned. | |
| MisconfiguredAuthEnvironment | -343 | The environment was not set up correctly for authentication = for example, no KDC could be found or the principal is unknown. | |
| UndocumentedSecurityLibraryStatus | -344 | An undocumented SSPI or GSSAPI status code was returned. | |
| ResponseBodyTooBigToDrain | -345 | The HTTP response was too big to drain. | |
| ResponseHeadersMultipleContentLength | -346 | The HTTP response contained multiple distinct Content-Length headers. | |
| IncompleteSpdyHeaders | -347 | SPDY Headers have been received, but not all of them - status or version headers are missing, so we're expecting additional frames to complete them. | |
| PacNotInDhcp | -348 | No PAC URL configuration could be retrieved from DHCP. This can indicate either a failure to retrieve the DHCP configuration, or that there was no PAC URL configured in DHCP. | |
| ResponseHeadersMultipleContentDisposition | -349 | The HTTP response contained multiple Content-Disposition headers. | |
| ResponseHeadersMultipleLocation | -350 | The HTTP response contained multiple Location headers. | |
| SpdyServerRefusedStream | -351 | SPDY server refused the stream. Client should retry. This should never be a user-visible error. | |
| SpdyPingFailed | -352 | SPDY server didn't respond to the PING message. | |
| PipelineEviction | -353 | The request couldn't be completed on an HTTP pipeline. Client should retry. | |
| ContentLengthMismatch | -354 | The HTTP response body transferred fewer bytes than were advertised by the Content-Length header when the connection is closed. | |
| IncompleteChunkedEncoding | -355 | The HTTP response body is transferred with Chunked-Encoding, but the terminating zero-length chunk was never sent when the connection is closed. | |
| QuicProtocolError | -356 | There is a QUIC protocol error. | |
| HeadersTruncated | -357 | The HTTP headers were truncated by an EOF. | |
