```
    Failed to import a client certificate from the platform store into the SSL library.
  - ICANN_NAME_COLLISION
```
public static final NetError ICANN_NAME_COLLISION
```
    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.
  - SSL_SERVER_CERT_BAD_FORMAT
```
public static final NetError SSL_SERVER_CERT_BAD_FORMAT
```
    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.

```
public static final NetError CT_STH_PARSING_FAILED
```
    Certificate Transparency: Received a signed tree head that failed to parse.

```
public static final NetError UNABLE_TO_REUSE_CONNECTION_FOR_PROXY_AUTH
```
    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.

public static final NetError CT_CONSISTENCY_PROOF_PARSING_FAILED
```
    Certificate Transparency: Failed to parse the received consistency proof.
  - SSL_OBSOLETE_CIPHER
```
public static final NetError SSL_OBSOLETE_CIPHER

    The SSL server required an unsupported cipher suite that has since been removed. This error will temporarily be signaled on a fallback for one or two releases immediately following a cipher suite's removal, after which the fallback will be removed.
  - WS_UPGRADE
```
public static final NetError WS_UPGRADE
```
    When a WebSocket handshake is done successfully and the connection has been upgraded, the URLRequest is cancelled with this error code.
  - READ_IF_READY_NOT_IMPLEMENTED
```
public static final NetError READ_IF_READY_NOT_IMPLEMENTED
```
    Socket ReadIfReady support is not implemented. This error should not be user visible, because the normal Read() method is used as a fallback.

public static final NetError NO_BUFFER_SPACE
```
    No socket buffer space is available.
  - SSL_CLIENT_AUTH_NO_COMMON_ALGORITHMS

    There were no common signature algorithms between our client certificate private key and the server's preferences.
  - EARLY_DATA_REJECTED
```
public static final NetError EARLY_DATA_REJECTED
```
    TLS 1.3 early data was rejected by the server. This will be received before any data is returned from the socket. The request should be retried with early data disabled.
  - WRONG_VERSION_ON_EARLY_DATA
```
public static final NetError WRONG_VERSION_ON_EARLY_DATA
```
    TLS 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.
  - TLS13_DOWNGRADE_DETECTED
```
public static final NetError TLS13_DOWNGRADE_DETECTED
```
    TLS 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.;
  - SSL_KEY_USAGE_INCOMPATIBLE
```
public static final NetError SSL_KEY_USAGE_INCOMPATIBLE
```
    The server's certificate has a keyUsage extension incompatible with the negotiated TLS key exchange method.
  - CERT_COMMON_NAME_INVALID
```
public static final NetError CERT_COMMON_NAME_INVALID
```
    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.
  - CERT_DATE_INVALID
```
public static final NetError CERT_DATE_INVALID
```
    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.
  - CERT_AUTHORITY_INVALID
```
public static final NetError CERT_AUTHORITY_INVALID
```
    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).
  - CERT_CONTAINS_ERRORS
```
public static final NetError CERT_CONTAINS_ERRORS
```
    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.
  - CERT_NO_REVOCATION_MECHANISM
```
public static final NetError CERT_NO_REVOCATION_MECHANISM
```
    The certificate has no mechanism for determining if it is revoked. In effect, this certificate cannot be revoked.
  - CERT_UNABLE_TO_CHECK_REVOCATION
```
public static final NetError CERT_UNABLE_TO_CHECK_REVOCATION
```
    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.
  - CERT_REVOKED
```
public static final NetError CERT_REVOKED
```
    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.
  - CERT_INVALID
```
public static final NetError CERT_INVALID
```

  - CERT_WEAK_KEY
```
public static final NetError CERT_WEAK_KEY

```
    The certificate claimed DNS names that are in violation of name constraints.

```
    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).

  - TOO_MANY_RETRIES
```
public static final NetError TOO_MANY_RETRIES
```

    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.

    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.

    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).
