Using RT-AC86U/Merlin 384.4_2 with OpenVPN client on NordVPN
Running a full week without a glitch very well and very fast.
During night time (no users active) I got this "connection timing out" router/openvpn did not manage to re-connect after this which only could be done (hours later) with a router's reboot.
Syslog entries:
Apr 29 01:54:16 ovpn-client1[1535]: Control Channel: TLSv1.2, cipher TLSv1/SSLv3 ECDHE-RSA-AES256-GCM-SHA384, 2048 bit RSA

From here, log is repeating itself without a end for many hours with same kind of entries.
After the normal “Control Channel” (first line) entry in syslog it took some 25 minutes before getting the next entry “Inactivity timeout”.
After that, connection was not restored and only a router reboot by hand, restored things.

Do the log entries tell something what is going on and where or is it just a bit or byte falling somewhere and router/openvpn failing to pickup/restore after that? Is there a way to restart connection automaticaly?
NordVPN advices to use TCP protocol instead of UDP but before doing that,
like to check if this problem is known or more common.
