failed to start grpc server

Thanks, this does give me a little more insight. My initial guess is that something else is bound on that port (or the app crashed and OS still treats it as bound). Can you try changing it in the settings (anything between 50000 to 60000 should work)? Rebooting your phone can also help. Other than that, I think MIUI has an option to block network/internet access for some apps, which could also be causing the problem.

I also had this Problem. I can confirm that changing the port or rebooting the device works!
I have a Samsung Smartphone with Android 12 and OneUI-Version 4.1

Motorola stock ROM phone here. I also had this problem when I upgraded to 1.6 but a reboot fixed it. However. A reboot shouldn't be necessary and if a port was being blocked somehow, a reboot wouldn't be enough. You'd have to change the port. There is more to this issue than we understand but I'm glad we still have an open issue for it.

Hi, yes, I've heard about this already but I don't know yet what causes it. Could you please try installing this debug build and obtaining a debug log (as described in connection-issues.md)? It would be much appreciated.

Hello,
from debug logs I can see

java.io.IOException: Failed to bind to address ::/:::42000

Trying on xiaomi miui. Tested that 5353(udp) and 42000(udp) are reachable (from pc) 42000(tcp) is indeed not responding.

Will this help?

Hello,
when I updated to version 1.6, I had this problem. It was working normally before.

In any case, I followed my friends' advice to restart the device and everything worked again.
