Before starting, please take a moment to prepare your environment:

If you still have local access to the server (e.g., via a monitor and keyboard), you can use the built-in GUI mode to reconfigure settings without deleting files: Boot into GUI Mode : Select "Unraid OS GUI Mode" from the boot menu. Update Settings : Navigate to Network Settings to manually adjust or reset your configuration.

If you encounter issues after resetting your network settings:

You enabled VLANs, and the switch port isn't configured correctly.

If you have a monitor and keyboard attached to the server (GUI or Terminal mode), you can reset without removing the USB: Log in as root . Type the following commands:

When you cannot access the Unraid web interface, the most reliable fix is to delete the network configuration file directly from the boot media. Unraid will automatically generate a fresh, working default file on the next boot. Step 1: Power Down Your Server safely
