Lost connection to the server

Information on your n8n setup

  • n8n version: 1.98.2

Normally the issue is that websocket support is not enabled in the reverse proxy.
Can you have a look and see if you enabled it?

I have enabled it.

part of the lines in the apache2 proxy reverse config file

ProxyPass /rest/push wss://10.x.x.x:5678/rest/push
ProxyPassReverse /rest/push wss://10.x.x.x:5678/rest/push

But still not working. how to ensure the websocket path is correct?

I found the path in the developer mode in the chrome browser

index–ag0tEQM.js:299938 WebSocket connection to ‘wss://xxxxx.ddns.net/rest/push?pushRef=brncv8v7vc’ failed:

Thanks!
