@pitaj OK, I have no idea what's going on, but after I verified all of those things, without actually changing the code that wasn't working before... suddenly I'm getting user messages! 😕 😕 😕
So... yeah, it's working now. Thanks for the help!
I got this error in browser client, don't know what it will take affect and how to solve?
WebSocket connection to 'ws://<myhost>/socket.io/?EIO=3&transport=websocket&sid=wW5Z4UKR9a_ZHKHkAAAF' failed: Error during WebSocket handshake: Unexpected response code: 400
which port it's using, I just open the port 4567 in firewall.
