Hello guys, I have a problem and I would like to know if anyone has been through something similar.
I'm using SIGNALR to develop a chat application similar to Whatsapp, everything works fine, the point is that I found that when the cell phone is at 3g / 4g I can't establish communication with the server's HUB, this in the Android project. On the Android emulator it even works, but on my phone (Xiaomi MI 9) it doesn't. It displays this error: "unable to complete handshake with the server due to an error: handshake was canceled."
Has anyone ever experienced this?
