Background; I have two ubiquiti routers deployed to a particular site. The VPN config worked on these to connect back to our data center, tested in our office and they worked for a couple weeks on site. Four days ago both went down at the same time. Both were still connected to UNMS though. I ssh into one via UNMS and poked around but didn't see anything wrong, so I told it to reboot but it never reconnected to UNMS, or OpenVPN. The second one is still on UNMS and the logs in it and the server look like this.
Client Log;
