Sudden loss of peers after months of working

I’m using Mikrotik to connect a couple family starlink sites so we can share Plex and a NAS, it’s been working for several months (like since September 23). Yesterday or the day before, one of the sites magically lost connection. It shows no path info on the peers side. I verified all other internet functions are working, and I can resolve my.zerotier.com and I’ve tested outbound port 9993 is open and working. Anything else I should be checking? It’s the only site that went down, and I’ve tried reboots, removing the instance and re-adding it. I know it’s something that should go to Mikrotik for support, but I figured I’d try here first just in case.
