What did you make right before losing access?

Locate and (or rename to .bak for safety) these files: network.cfg network-rules.cfg (if present) 3. Reboot and Reconnect

If resetting the network configuration does not solve your problem, the issue may be caused by a problematic plugin. To test this theory, you can boot your Unraid server in . When you see the Unraid boot menu on your monitor, select the "Unraid OS Safe Mode (no plugins, no GUI)" option.

After resetting, your Ethernet ports might be mapped differently (e.g., eth1 instead of eth0 ). Head to in the Unraid GUI to re-assign your interfaces and re-apply any static IPs or VLANs you previously had.
