HELP - My Unraid server cannot connect to the outside world

[tknx]

Fix Common Problems is having troubles connecting to github, if I try to ping google.com from the command line, it fails too.

No idea why this is happening!

Remove the gateway from eth1, also eth0 should be you main NIC, does the 10GbE NIC have internet access?

Hi @Jorge

 

Yes - it does have internet access through eth0.

 

eth1 doesn't have anywhere to clear a gateway from?

 

[JorgeB]

Yes, I misread the config, looks like you have a vlan, suggest renaming network.cfg to go back to defaults just to test if makes any difference.

[tknx]

Ok. I renamed network.cfg and by default I still get errors on ping

Connect the gbit NIC to a router, set it as eth0 and see if that one works.

[tknx]

No luck there either.... This is pretty frustrating!

Nothing wrong the I can see, are you sure the router is correctly configured? Make sure the connection is a simple as it can be to start, no firewall, etc, just the server connected directly to the router.

[tknx]

Well now when I change network settings the UI entirely crashes, what a mess...

[tknx]

@JorgeB tried direct connect same problem. My Caddy reverse proxy works fine to get into the services onto the machine from outside.

 

I cannot ssh into the machine remotely either but can use the webUI based terminal.

 

[JorgeB]

Boot with a different flash drive using a new stock Unraid install, no key needed, just to rule out any config issue. 

[tknx]

@JorgeB

 

Used a fresh install and can ping (although it seems slow). So definitely feels like an Unraid problem, at least partially.

It suggests a config problem, you can either redo the flash drive and copy only the bare minium from the old /config folder (key, super.dat and pools folder) and reconfigure the rest of the server or copy that then start restoring the other config files one by one, or a few at a time to see if you find the culprit.

[tknx]

Yeah - I will try and copy over the files as you suggest to my install.

 

This is totally weird, right?

[tknx]

@JorgeB

So it worked fine until I started adding dockers back. I added Jellyfin and then I could not connect or add any other dockers or ping.

 

So either it is that particular config or it is the docker service itself?

Solved it sort of - it was Wireguard.

 

I think when I added 0.0.0.0/0 to allowed peers, it created problems. I need to experiment more with it since i want VPN clients to be able to access both my VLANs
