Description

Issue template (remove lines from top till here)

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?

Research direction

Start by checking the zerotier service state and running zerotier-cli info after the node becomes OFFLINE, then compare relevant service and firewall logs with the working state after a restart. Reproduce the multi-day failure if possible; done means identifying the cause of the offline transition and verifying that the service remains ONLINE without a manual restart.
