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.
CertCommonNameInvalid = -200The 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.
CertContainsErrors = -203The 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.
CertDatabaseChanged = -714The certificate database changed in some way.
CertDateInvalid = -201The 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.
CertEnd = -220The value immediately past the last certificate error code.

.local.CertTransparencyRequired = -214Certificate Transparency was required for this connection, but the server did not provide CT information that complied with the policy.
CertUnableToCheckRevocation = -205Revocation 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 An attacker has compromised the private key in the certificate and is blocking our attempt to find out that the cert was revoked.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.
CertValidityTooLong = -213The certificate's validity period is too long.
CertVerifierChanged = -716The certificate verifier configuration changed in some way.

SslClientAuthSignatureFailed = -141We 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.

SslDecryptErrorAlert = -153An SSL peer sent us a fatal decrypt_error alert. This typically occurs when a peer could not correctly verify a signature (in CertificateVerify or ServerKeyExchange) or validate a Finished message.

SslPinnedKeyNotInCertChain = -150The 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.
SslProtocolError = -107An SSL protocol error occurred.
SslRenegotiationRequested = -114The server requested a renegotiation = rehandshake,.
SslServerCertBadFormat = -167The SSL server presented a certificate which could not be decoded. This is not a certificate error code as no X509Certificate object is available. This error is fatal.

TimedOut = -7An operation timed out.
Tls13DowngradeDetected = -180TLS 1.3 was enabled, but a lower version was negotiated and the server returned a value indicating it supported TLS 1.3. This is part of a security check in TLS 1.3, but it may also indicate the user is behind a buggy TLS-terminating proxy which implemented TLS 1.2 incorrectly. (See https://crbug.com/boringssl/226.)
TooManyAcceptChRestarts = -382The
ACCEPT_CHrestart has been triggered too many times.TooManyRedirects = -310Attempting to load an URL resulted in too many redirects.
TooManyRetries = -375An HTTP transaction was retried too many times due for authentication or invalid certificates. This may be due to a bug in the net stack that would otherwise infinite loop, or if the server or proxy continually requests fresh credentials or presents a fresh invalid certificate.
TrustTokenOperationFailed = -506A Trust Tokens protocol operation-executing request failed for one of a number of reasons (precondition failure, internal error, bad response).
TrustTokenOperationSuccessWithoutSendingRequest = -507When handling a Trust Tokens protocol operation-executing request, the system was able to execute the request's Trust Tokens operation without sending the request to its destination: for instance, the results could have been present in a local cache (for redemption) or the operation could have been diverted to a local provider (for "platform-provided" issuance).
TunnelConnectionFailed = -111A tunnel connection through the proxy could not be established.
UnableToReuseConnectionForProxyAuth = -170The attempt to reuse a connection to send proxy auth credentials failed before the AuthController was used to generate credentials. The caller should reuse the controller with a new connection. This error is only used internally by the network stack.

UnknownUrlScheme = -302The scheme of the URL is unknown.
UnsafePort = -312Attempting 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,.

UnsupportedAuthScheme = -339An HTTP Authentication scheme was tried which is not supported on this machine.

WinsockUnexpectedWrittenBytes = -124Winsock sometimes reports more data written than passed. This is probably due to a broken LSP.
WrongVersionOnEarlyData = -179TLS 1.3 early data was offered, but the server responded with TLS 1.2 or earlier. This is an internal error code to account for a backwards-compatibility issue with early data and TLS 1.2. It will be received before any data is returned from the socket. The request should be retried with early data disabled. See https://tools.ietf.org/html/rfc8446#appendix-D.3 for details.
WsProtocolError = -145Websocket protocol error. Indicates that we are terminating the connection due to a malformed frame or other protocol violation.
