Unraid server no internet connection - router does not see server

[3llipsoid]

Hello all, I am hoping someone can help me figure out my issue.

 

To make a long story short I was having issues getting direct play to work with Plex on my TV. Looking through Plex I noticed the server would frequently show as offline. Eventually Plex simply could not see the server at all. I eventually stumbled on a forum post that suggested rolling back to 6.11.5 - I figured I would give it a try.

 

Reverting to 6.11.5 did not solve the issue and I now noticed (this may have been the case prior to the roll back, I simply didn't pay attention) that the app addresses for my Dockers were no longer 10.0.0.44 but were now 172.17.0.x . I tried stopping and restarting Docker, I rebooted the server a couple times and no change. I tried pinging google.com from the containers and got nothing. The containers were originally on a custom docker network, I tried moving them to host - again no change.

 

When I try changing back to the original custom network I now get an iptable error

docker: Error response from daemon: driver failed programming external connectivity on endpoint radarr_uhd (a41788fbba829d88411c5ed082aaedf9c984de6ff1d44d87716d7743bf2fca87): (iptables failed: iptables --wait -t filter -A DOCKER ! -i br-785c0d48ae69 -o br-785c0d48ae69 -p tcp -d 172.18.0.2 --dport 7878 -j ACCEPT: iptables: No chain/target/match by that name.

 

I can ping the server from my desktop no problem, but my router shows the mac address for my server as offline.

 

I am honestly at a loss and any help/direction would be greatly appreciated. Attached is the diagnostics zip file.

 

Edit: I forgot to mention that while I can access the web GUI and ping the server, I can't access any of my shares over the network.

additional info

Doing a factory reset of the router seems to have addressed the network visibility as I am now able to see it both in the router and have access to the shared drives over the network.

 

I was briefly able to reach the internet but that ability has quickly gone away.

setting the IPv4 DNS server assignment to static and adding in 8.8.8.8 seems to have resolved the issue. I had tried this earlier with no success.

 

Everything appears to be working, but I have no idea why.
