Hello. This happens in windows when the screen goes off because of inactivity as defined in power settings. The client dies immediately, fortunately the state on the server is not lost. To reproduce just turn off screen after 1 minute, wait, when screen off wait for a few more secs. Then log in again and XPRA will no longer be there.
This is my command line in windows:
"C:\Program Files\Xpra\Xpra.exe" attach tcp://172.17.151.234:10000/ --compressor=none
Server: xpra v3.0.9-r26111
Server operating system: Linux marcelo-vm 5.3.0-46-generic #38~18.04.1-Ubuntu SMP Tue Mar 31 04:17:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
Client:
Xpra 3.0.9 Python 3.8, 64bit revision 26113 built on Win7Pro64-PC by Win7 Pro 64 2020-04-13 17:35 using Cython 0.29.16 gcc (Rev2, Built by MSYS2 project) 9.3.0
I will attach a log of the client with "-d all"
Had to split the log in two parts, think the second part is the most interesting though
This is not a bug, from your log:

The connection is closed, so the client exits.
The only thing we could do is to add an 'auto-reconnect' option, feel free to create a ticket for that.
But why is the connection dying all the time? Are you sure this is completely unrelated to XPRA? (this is a local connection to a virtual machine running on the same computer, unrelated to network access)
But why is the connection dying all the time?
Is this all the time or just when power settings kick in?
Are you sure this is completely unrelated to XPRA?
Absolutely, the WinError 10051
comes from the OS: Windows Sockets Error Codes: WSAENETUNREACH 10051: Network is unreachable. A socket operation was attempted to an unreachable network. This usually means the local software knows no route to reach the remote host.
this is a local connection to a virtual machine running on the same computer, unrelated to network access
This local connection may still be taken offline when the power saver does its thing.
