A response code of 502 indicates that the server acting as a gateway or proxy received an invalid response from the upstream server it accessed to complete the request. This can occur due to several reasons, including network issues, server overload, or incorrect server configuration.
To resolve this error in a WebSocket connection, you can try the following steps:
Check the URL: Ensure that the WebSocket URL is correct and points to a valid endpoint.
Check the server status: Verify that the server hosting the WebSocket endpoint is running correctly and is not overloaded.
Check network connectivity: Confirm that there are no network connectivity issues between your client and the server, such as firewall or routing problems.
Restart the server: Sometimes, restarting the server can clear any temporary issues causing the error.
Contact support: If none of the above steps work, contact the support team responsible for maintaining the WebSocket endpoint for further assistance.
