I got many “no route to host” and “connection reset by peer” lines constantly in /var/log/syslog. The zerotier network seems OK/working though.
zerotier 1.10.6 from zerotier’s official apt repo, running on Ubuntu 22.04.3 LTS (x86_64) and raspbian GNU/Linux 11 (bullseye) (armv7l).
I am wondering what could cause these warnings.
