Not connecting to network

[BigMal]

With explaination, my server stopped connecting to the network.  All other devices o the network are connected fine, it's just unRaid.  It does not appear to be getting an address from my router, which I already reset.  Connecting via a monitor and keyboard with the GUI, I tried deleting the network-rules and network cfg files.  For whatever reason, it will not get an address and setting a static IP address does not work either.  I've attached my diagnotics file.  Any support or pointers would be greatly appreciated.

NIC is failing to get an IP from the router, this is not usually an Unriad issue, try a different cable, and make sure it's connect directly to the router.

Tried another cable already and that didn’t help. Another devices are getting IPs from the router without issue.

Like mentioned unlikely that the server is the problem, unless the NIC is bad, try with an add-on NIC if available.

Thanks! Agree, I don’t think it’s the server either. I believe I’ve got another NIC a I can use to at least test. Appreciate the help.

Came back to update.  Not related to Unraid at all.  Just got a Mac and connected via a docking station (which is hardwired to network) and it's related to that.  For whatever reason, it's causing issues when I disconnect it - it causes all hardwired connections to lose connectivity to the network.  Plug it back in and everything is fine again.  So, I need to work on that if I wish to operate via wired.
