It seems that just about every "inexplicable issue involving network communication" issue recently is because Windows keeping putting one or both computers in the public network and you have to switch it to work/private. It maybe not be it and in this case it's only one computer/side, but it's the first thing I check no matter what the issue nowadays. Happening to workstations, servers, machines that haven't been on a new network in years. Given that VPNs jump networks, it's worth a 30 second check.
