Problem

A single PC in the center is unable to boot, and it cannot be deleted from the ggRock Web UI.

The error message displayed may indicate "no more network devices".

Solution

1. Within the ggRock Web UI, look for the Machine that will not boot. It should have an unchanging number of Sent/Received bytes (usually under 1 MB).

2. Run this command from the ggRock Server Console to view open TCP connection for your stuck Machine: ss -H -t4n state established "( sport = :3260 and dst = YOUR_PC_IP_ADDRESS )" (don't forget to replace YOUR_PC_IP_ADDRESS with IP address of stuck Machine.

3. You should see one or two stuck connections. Last column will display your stuck Machine IP and then destination port, which you will need to kill the connection.

4. Run ss -K dst YOUR_PC_IP_ADDRESS dport = CLIENT_PORT_FROM_STEP_3
