I am using a GL.iNet Flint 2 with the original GL.i.Net firmware, updated to the latest available version (v24). I’ve noticed that after rebooting the router, I must manually log into the admin interface and stop/start the DDNS service. If I don’t do this, the WireGuard VPN is unable to resolve the new public IP address.
Even after 24 hours, I can't connect to the router via wireguard if I don't stop and start manually the ddns service
