NordVPN via OpenVPN

[fbeye]

Hello!

So I have followed NordVPN's guide to a T. It works, and it works well.
But I have noticed at times my whole network will show as UP but nothing can resolve.
I disconnect the NordVPN Interface and all resumes... I reconnect the NordVPN Interface and it goes back to normal.
The only errors I see are;

Code: [Select]

023-04-25T16:42:56-07:00 Error openvpn_client1 write UDPv4: Can't assign requested address (code=49)
2023-04-25T16:42:56-07:00 Error openvpn_client1 write UDPv4: Can't assign requested address (code=49)
I mean I know things just disconnect and sometimes do not come back up as we wish.. I am just wondering if anyone has seen this and there be something I can do? Those errors were from 3 or so days ago, and I left disconnected.
Upon reconnecting, I get these WARNINGS..Could they be leading into the errors?

Are any other interfaces in the 10.0.0.0/8 address space, per chance? In my experience, NordVPN typically assigns IP addresses dynamically in this address space with a /24 CIDR suffix. It could be different for the server(s) you connect to, so YMMV. Perhaps check what you are being assigned and compare to your other interfaces and see if they are too close for comfort...

You also might want to reboot.
