@User have you noticed any issues with windows clients behaving oddly after sleeping? I have one that has lost the ability to communicate with two other nodes, both remote, but can still ping another two remote nodes. It did this earlier today as well. Rebooting makes no difference, only leaving and joining the network again. This seems to rule out firewall issues. The logs in the netclient show no error, and wireguard seems to be handshaking and keeping alive the connection to one of the nodes, but isn't showing any attempts on the other one. I'm not sure its sleeping that's the issue, but this was a common factor in both situations
