Today I noticed that I could not access a server I have overseas via ZeroTier. But the server is fully pingable over the plain internet and all of it’s exposed services are fully reachable - https/SSH/etc.
I went in to take a look and ran “ifconfig” and noticed that the usual ZeroTier network interface was now missing! I cannot ping what should be it’s local ZeroTier IP address but again: it is fully pingable from multiple other devices, servers and locations over the regular internet.
The MyZeroTier website does display it as being online and having the same IP address.
I went ahead and uninstalled ZT and removed its directory from /var/lib - reinstalled, restarted a few times and nothing has changed.
How can I restore the ZeroTier network interface and connectivity over ZT?
