Flutter Web - can not authorized

[MarceloRab]

Exactly the same thing that happens to me. I've been trying for 8 hours and nothing. 😒. Web app on localHost and Android works perfectly.

Only on flutter web and with server it doesn't work..❗

Site = > https://.... (Vercel)
Server = > https://... (Render)

My versions.
Flutter 3.19.0
Dart 3.3.0
socket_io_client 2.0.3+1

All these measures did not work.

1. Downgrade Socket.io node from 4.7.4 => 4.6.2. 👉 Doesn't work

2. Flutter = >

IO.io(socketUrl, <String, dynamic>{ 'autoConnect': false, 'transports': ['websocket'], 'rejectUnauthorized': false, 'withCredentials': false, });

👉 Doesn't work

3. Node Server = >

this.io = new socketIo.Server(this.server, { colors: { origin: [ ''my_cors", //"*", ], credentials: false,

👉 Doesn't work

Error thrown ▶ timeout in all states.
