During my issues one of my troubleshooting steps was to add a USB Ethernet adapter to the system, and configured it's networking options in the network options config file on the USB config/network.cfg (made an educated guess that the next adapter added would be eth4)- I was then able to access the GUI- didn't fix the br0 problem, but did bypass it enough for me to investigate from the GUI.

I just ran into a similar problem today after upgrading to 7.1.3 - Fun thing I noticed was that the VM's I have sharing the primary adapter were working fine, but no ping response or ssh on the servers static IP. I threw the problem at Perplexity and got this response which got me up and running, just had to pull the USB and modify /boot/config/go on another system- Network Configuration Issues br0 Interface Instability The main interface (br0) losing connectivity after a few minutes while VMs remain active aligns with a known issue in Unraid 7.1.3 where the br0-shim interface isn't consistently created. This was partially addressed in the 7.1.3 update but might require manual intervention. Add these commands to your /boot/config/go file for persistence across reboots: bash ip link add shim0 link br0 type ipvlan mode l2 ip addr add 192.168.50.11/24 dev shim0 # Match br0 IP ip link set shim0 up
