Does it start to happen at specific events or times?

This problem still exists in version 3.1.1-46-g06c489f. I enabled the -S2 parameter. 10/Jul/2022 12:44:54 [edge_utils.c:1568] WARNING: supernode not responding, now trying [0.0.0.0:1111]

Planning to go through the network code anyway, I will have a closer look soon. It looks as if the socket is not ready yet / again.

I have to add that TCP was added later so it was kind of retro-fitted into existing code which even still does not work at all on Windows. So yes, TCP is still somewhat unreliable...
