My OpenVPN installation on OMV 4.1.23-1 Arrakis stopped working a few weeks ago, and I have tried to troubleshoot by searching through forums and digging through client/server settings. Still not working.
This evening, I uninstalled and reinstalled, removed and replaced certificates, but I have not made it work.
My OMV installation is on a Thinkserver TS140, and up to date on OMV 4. I only run NAS for my family, and serve media through PLEX. I maintain a 3-2-1 backup strategy. I use and OpenVPN client on iOS, and through Tunnelblick on MacOS.
My iOS client suddenly stopped working this summer, and I also noticed that my MacOS client wouldn't connect. I verified that my installation hadn't changed AFAIK.
I need expertise help, please!
