Maintainer: @mwarning
Environment: MediaTek MT7621, OpenWrt 22.03.3

Zerotier version: 1.12.1-1 (latest)

After some days of work, my zerotier node goes OFFLINE (zerotier-cli info shows OFFLINE and I cannot reach the device from outside, also the zerotier one dashboard shows it offline).

Restarting the zerotier service (without reboot the router or anything else) temporary fixes the issue.

My firewall is configured properly (otherwise restarting the service wouldn't do anything), any help?

Can you execute the "logread" command and look at the logs? Also the output of "dmesg" might help. Maybe it is a memory leak. It is hard to tell..
