Upgrade to 7.2.1 from 7.0. Everything seemed to go smooth. Server just sat doing it's thing until I wanted to watch a show on my Emby. Normal I access it with a domain with rever proxy and all that. Has worked for over a year no issues. Could not access it. Tried to just run it with the local ip to the docker and worked fine. Jumped on server and noticed that APPS can't access the WWW either. It is looking like Everything works fine locally but the server itself can't access outside.

Fiber Modem/Router (AT&T) - Ethernet to Server. I use Cloudflare/Reverse Proxy to access my services. Again, haven't had any issues until after upgrading. I turned off Docker and VMs to see if it would make a difference; nothing. Attached is Diag.

I am not sure where to go from here on fixing this issue beside maybe downgrading back to 7.0.

There are two gateways configured; only eth0/br0/bond0 should have a gateway. Remove the other one and retest.

I am a beginner in a lot of this but after turning off VMs, Docker, and Wireguard I have this and still not working. Is there somewhere else I am supposed to make the change?

Network Settings - Routing Table

Edited December 6, 2025Dec 6 by bitphire

You only need to remove it from the network settings.

I'm in Settings -> Network Settings. for eth0 IPv4 default gateway is set. eth1 has same gateway as etho but is inactive, eth2 and eth3 are inactive with no gateway listed. Interface Extra br0 br1 are Current listening interfaces, include listening interface virbr0. Interface Rules just shows eth0-3 mac addresses. Routing table, see screenshot link in previous post.

I see at the bottom "Interface - Ethernet Port 1 is down. Check cable!" however, I only have 1 ethernet cable going to the server and it's on eth0. I believe wireguard setup the eth1.

I just don't know why my internet settings were changed during the upgrade. It's been working for a couple of years now with no issues.

ifconfig: 192.168.1.8 is the static ip of the server. 192.168.1.254 is the router/gateway.

Seems I had fixed it and did not even know it since docker and vms were turned off ><
