Error WebSocket connection 3000

[elbiozard]

Description of the bug:

I'm using the app inside a docker container with the port setting 8042:3000, since I'm using port 3000. I also use Ngnx Proxy Manager and access the app from bot.mydomain.com.
In the web console I get the following error:
WebSocketClient.js:13 WebSocket connection to 'wss://bot.mydomain.com:3000/ws' failed:
WebSocketClient @ WebSocketClient.js:13

I can't find where to change the port settings.

Actual vs expected behavior:
