Why do SSH connections via IPv6 break when the system goes into sleep mode?
As described here
https://github.com/zellij-org/zellij/issues/1781
I have issues with SSH connections when using IPv6 after Windows 10 goes into sleep mode.
client_loop: send disconnect: Connection reset
This is really strange. SSH connections with IPv4 are not affected. I also tested with several keepalive parameters for SSH.
I tried to disable this power save option in the device manager for this interface but this brought no change.
I have now also done a test from my Linux system: I can bring down the interface wait a minute and bring it up again. SSH connections survive this.
What could be the reason why SSH connections with IPv6 do not survive sleep mode?
