Everything was working fine. Upgraded routers and changed ddns name and now I'm having issues.
I changed ddns name in the openvpn plugin on openmediavault. Re-downloaded the certs and it won't authenticate. Port is opened with the correct protocol on the router. When I do an open port check online the it says the port is closed. I wasn't sure if that was normal to not show open because it's a vpn port or not. Plex and syncthing ports opened as it should.
