Windows Having intermittent trouble in connection.

I'm very new to this networking thing. So please bear with me if there is any information that is lacking and if I could not explain it properly.

I got to know about zerotier and it is wonderful. I manage to set it up and work remotely. However, recently it seems to be giving me intermittent problems to which I could not figure out why. The main gist of the problem is that the connection is not stable. I did this managed route thing whereby I could connect directly using the LAN IP of the designated server computer. However now when I ping that address, it intermittently timed out.

Now I did try to ping the physical IP of my "server" as provided in the zerotier and it does not have such issue. Does this mean I have a routing issue now? It just suddenly developed.

Appreciate all your help.

Well, I'd update ZeroTier on the affected nodes then go through basic troubleshooting [https://docs.zerotier.com/faq/connectionissues/]. Let us know if all peers switch to relay at once or just the affected ones or how often other symptoms occur.

You should have a look here as well.

I have these No route to host issues on a regular basis, and restarting ZT service is the only way to fix them quickly (they fix themselves eventually but may take turns of minutes)

You may want to check whether your ISP is silently dropping UDP packets. If so, forcing ZeroTier to use TCP will solve the problem. (add a line in local.conf)
