February 12, 20242 yr Hello, Switched on my Unraid server after a few days and found that the ethernet no longer seems to work and I have no idea why. I have attached my diagnostics file shortly before I turned the server off again. Any help fixing this issue would be much appreciated. Thanks in advance. tower-diagnostics-20240212-2221.zip
February 12, 20242 yr Community Expert Doesn't look like you're getting DHCP. Can you see your server on your router? Check ports, plugs, cables on server, switch, router.

No - I can’t see the server on my router. I tested the cable by taking it out and connecting this to my PC, which was picked up instantly. Therefore I believe it’s an issue on the server, but happy to be proven wrong.
February 12, 20242 yr Community Expert When you tested the cable, was the other end still connected the same way it was when it was connected to your server?

All I did was remove the cable from the server and put that same cable into the PC. I didn’t even remove the other end from my switch.

This probably explains why I’m seeing a red light when my ethernet cable is connected to one of the controllers, while it is green with the other. Unfortunately even if I switch to the other controller, I’m still not getting a connection.
February 14, 20242 yr Community Expert Solution You are getting an internal IP address, this usually means there's a problem or configuration issue with the DHCP server, usually your router.

I’m going to Google this as I don’t have much of an understanding of this or if you can expand that would be great. I’d be suspicious if my router is causing issues as no changes have been made to my router nor do I have problems with any other device at the moment.
February 14, 20242 yr Community Expert Probably a hardware problem, unless you are trying to use the Realtek. Did you check the port to make sure the pins are lined up?

Think my router was the issue in the end. Did a factory reset on my router and I'm all up and running again. Thanks again for your help
