December 20, 20232 yr When I went to sleep yesterday the server was working perfectly. Today I woke up and couldn't acces plex on my TV, I then realized that I couldn't even acces the unraid gui and any docker container I have. I went to check if the server was on and indeed it looks like it is. LEDs on, fans on, disks spinning, all seems good. Even the ethernet cable has the two LEDs on and blinking. I tested the cable with my laptop and it works. I then went to my router dashboard and my server doesn't show up there. It's not conected to my router, so naturally I wasn't able to access it. But I can't for the love of god understand why. I haven't changed anything overnight, and the ethernet cable works. I tried rebooting the server and it did fine. When I plug a display it tells me that the server is available at the usual static ip i gave it a year ago. I am clueless. Without being able to access it I don't know how could I get a error diagnostic or something to help you more. I haven't done any change to hardware in more than a year, and any change in software in weeks. The OS version is 6.12.5.
December 20, 20232 yr Author Is there something I can do to narrow down the options why this happened, or I can assume it is just faulty hardware on my server and I have to “replace” the NIC?
December 20, 20232 yr Community Expert It should be NIC, cable or switch, check the switch light for that port, and swap with a known good port and cable if possible.
December 20, 20232 yr Author I made sure the cable and switch are working. The problem is on the server side. The thing is, I just tried to plug ethernet through an ethernet adapter to usb 3.0, that way I am avoiding using the NIC on the server and the ethernet connection goes from the USB controller to the CPU, am I right? Anyway, it is not working anyway. The same problem. Does it give you more info to work around?

(The Gurus can check to see what NIC's have been detected, what they are assigned as, and status of the network situation.)
