WebSocket 1011 Internal Error vs 1014 Bad Gateway
Both WebSocket 1011 (Internal Error) and 1014 (Bad Gateway) belong to the WebSocket Close Codes category. 1011 indicates that the server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request. Meanwhile, 1014 means that the server acting as a gateway or proxy received an invalid response from an upstream server it accessed while attempting to fulfill the request.
