Hello!
I use zerotier for a long time and it always worked flawlessy with a great variety of networks, even double-nat configurations.
But in the last weeks, i’m facing some problems and need help…
The latency between my house and every node outside it became unstable.
Sometimes it’s very good (less than 20ms), but sometimes it’s above 200ms.
What i do in the case of high latency is restart the zerotier service in the nodes / restart the computers. (And it worked until yesterday).
i’m sitting now in the 200ms and can’t reduce it. But what’s is really strange, is that i’m not relaying to the zerotier servers. (or i think i’m not).

This is an output from a server in my house (i’m in my sister house now), and the node that i’m using is the “e6cbfe19c9”.

OBS: My house don’t have public ipv4 (it’s CGNAT) and don’t have ipv6 too (i know, it’s bad, but my ISP is a local one and i don’t have much options).
If you guys can help me, i’ll be really grateful!!
