SOLVED

Added

socket.io {"address": */*};

Default "address:" **; that's is problem.

Hi everyone

Trying to up nodebb in the private ipv6 sub network without domains.
Using docker + nginx. All works fine, but websocket not. "Connection has been lost".

First i'm try edit config.json, added socket.io origins. Error message in the web console disappeared but it doesn't help.

Nginx config is right. Another site with web socket working fine.

Can you help?

Thx
