certErrorInSslRenegotiation=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.

icannNameCollision=Resolving a hostname to an IP address list included the IPv4 address "127.0.53.53". This is a special IP address which ICANN has recommended to indicate there was a name collision, and alert admins to a potential problem.
incompleteChunkedEncoding=The HTTP response body is transferred with Chunked-Encoding, but the terminating zero-length chunk was never sent when the connection is closed.
incompleteSpdyHeaders=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.

sslClientAuthPrivateKeyAccessDenied=The permission to use the SSL client certificate's private key was denied.
sslClientAuthSignatureFailed=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to the private key, the private key may not be valid for signing, the key may be relying on a cached handle which is no longer valid, or the CSP won't allow arbitrary data to be signed.
sslDecompressionFailureAlert=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.

sslFallbackBeyondMinimumVersion=The SSL server requires falling back to a version older than the configured minimum fallback version, and thus fallback failed.
sslHandshakeNotCompleted=An operation failed because the SSL handshake has not completed.
sslInappropriateFallback=The SSL server indicated that an unnecessary TLS version fallback was performed.
sslNoRenegotiation=The peer sent an SSL no_renegotiation alert message.
sslPinnedKeyNotInCertChain=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.
sslProtocolError=An SSL protocol error occurred.
sslRenegotiationRequested=The server requested a renegotiation (rehandshake).
sslServerCertBadFormat=The 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.
sslUnrecognizedNameAlert=The SSL server sent us a fatal unrecognized_name alert.
sslVersionOrCipherMismatch=The client and server don't support a common SSL protocol version or cipher suite.

tunnelConnectionFailed=A tunnel connection through the proxy could not be established.
unableToReuseConnectionForProxyAuth=The 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.
undocumentedSecurityLibraryStatus=An undocumented SSPI or GSSAPI status code was returned.
unexpectedProxyAuth=The response was 407 (Proxy Authentication Required), yet we did not send the request to a proxy.
unexpectedSecurityLibraryStatus=An unexpected, but documented, SSPI or GSSAPI status code was returned.
unknownURLScheme=The scheme of the URL is unknown.
unrecognizedFtpDirectoryListingFormat=The server sent an FTP directory listing in a format we do not understand.
unsafePort=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).
unsafeRedirect=Attempting to load an URL resulted in an unsafe redirect (e.g., a redirect to file:// is considered unsafe).
unsupportedAuthScheme=An HTTP Authentication scheme was tried which is not supported on this machine.
winsockUnexpectedWrittenBytes=Winsock sometimes reports more data written than passed.  This is probably due to a broken LSP.
wsProtocolError=Websocket protocol error. Indicates that we are terminating the connection due to a malformed frame or other protocol violation.
wsThrottleQueueTooLarge=There are too many pending WebSocketJob instances, so the new job was not pushed to the queue.
