Hey guys I had this weird issue pop up out of nowhere over the past few days where my connectivity on my unRaid server will just disconnect for a few seconds then reconnect. I noticed this when watching a movie where it was buffering quite frequently. When this occurred I tried to open my unraid dashboard but it took much longer than usual to login. 

Checking the logs soon after I seen this which tells me the network is falling over.

I replaced the ethernet cable from my server did some testing it and it continues. Nothing was changed on my server nothing new added. 

 

I got an Ubiquiti network in my home - Switch is a 16 Port PoE 150W. Nothing else on my network disconnects it's just my unraid server. 

 

Full diagnostics attached. I do have another ethernet port in my wall that I could use so I will put it in that keystone and see if it continues. 

I've also setup Uptime Kuma to monitor and sure enough you can see where it's gone down. Does anyone have any ideas?

I've had it connected to the ethernet port in my wall next to the one it used to be in and so far no drops in connectivity. So, i need to find out if it's something that happen to the keystone behind the wall plate, or it's something at the patch panel.
