Socket Disconnection issue on Specific Mobile Network on JIO 5g network in INDIA

Socket.io Version 4.7.2 in NODEJS

Best http socket.io client Version 2.8.6

Platform we are using Unity3d 2021.3.27f1

Hi Team,

we are using above version for creating socket connection for our game.

The socket is working fine on all other mobile networks and WIFI except JIO 5G network in INDIA.

Once we connect the socket using JIO 5G network. The socket get disconnected multiple times without any reason and this is happens only on JIO 5G Network.

Please let us know how to resolve it

Start by inspecting Assets/LUDO/Scripts/Common/SocketController.cs at line 219 and the BestHTTP WebSocket, TLS, and HTTP stack traces included in the report. Reproduce the disconnect on JIO 5G and a control network, then narrow down whether the cause is in the client, Socket.IO server, or network path. Done means a confirmed cause with a reproducible fix or documented external-network limitation.
