How to reconnect my client socketIO to my web server using ExpressJS and SocketIO

[Jonathan64340]

Hello everyone, today i'm needed help from you.
I have making one chat app using socketio front/back.
When i lost connection due to exemple switching from my wifi to my data mobile phone, i am disconnected but when i see in my network i can see the client socketIO try to reconnect on ws://{my_server} but my server using expressJS and i must call only https://{my_server} and not ws://{my_server}

Thank you all for your help !!!!

Hi! This is the expected behavior, the Socket.IO client will try to reconnect with either:

• HTTP long-polling, with URL like https://{my_server}
• or WebSocket, with URL like ws://{my_server}

Please see here: https://socket.io/docs/v4/how-it-works/

Or are you talking about the ws:// (no TLS) vs https:// (TLS)?
