Yes, this is using the proxy server offered with the 'xpra.socket' systemd unit 
provided by your xpra RPM packages. I'll try to capture logs from the proxy server.

I understand you have sessions running for days. I can leave an idle session with 
idle appliations open for days. The issue is only when applications are in use. I 
can leave active SSH sessions open for days. I haven't taken packet captures yet, 
but I doubt this is an OS or firewall issue.
