Websocket Connection Error 503 - Postman

Sascha 9 months ago

Hello,
when I try to establish a WebSocket connection with Postman I get the error

Could not connect to ws://192.168.178.20/api/socket
Error: Unexpected server response: 503

Otherwise the server works quite normally, I can access API with GET / POST. Why could that be?

There is no port number needed ?
