Strange disconnect issue between servers

[wwparker]

I'm running Tabby on a Windows 11 desktop that is connected using WiFi. When I connect to FreeBSD that I host in a colo, the connect stays active for days. I also have a FreeBSD server sitting in the garage that connected using a second WiFi mesh node. Connections that server disconnect after short timeouts. I've tried setting the Keep Alive, but that doesn't seem to make a difference. How would get the local ssh connections to FreeBSD server to not timeout so fast?
