I’ve got a client with an old Windows Small Business Server 2011, which is based on on Server 2008 R2. I installed Zerotier and noticed it is intermittently losing connection. Sometimes it loses its connection completely. After a service restart, it goes back to the same intermittent behaviour as before. The ZT web control panel shows no connectivity loss. The GUI and CLI also report they are connected.
I installed a tool called PingInfoView, which is a GUI ping tool that keeps history and stats. Over a roughly 10 hour period, it reported a 56% ping success rate. Looking at the history, I noticed that most of the time it goes in cycles of 10 mins connected and then 10 mins disconnected/not working. This behavior repeats the 10 mins cycles strangely like clock work. There are a few stretches of the ping failing in the middle of an “on” cycle though, so the cycle did not go uninterrupted for the whole 10-ish hours.
Anyways, would anyone have any ideas how to troubleshoot this? If I can’t figure this out, I was thinking of spinning up a small Linux VM on another server to run a ZT bridge. I was thinking of using Ubuntu server. Would there be another Linux distro that would be easier to setup?
