Possible Reason:

Your server’s host file may have been edited to block the domain name or IP address of your server.


Go to C:\Windows\System32\drivers\etc Right click the hosts file and click on Run as administrator to open the notepad.

Then remove all the IP with non-routable meta address and save the host file. Restart your computer if it did not work.

After restarting, the USB Key Server Monitor will be working as intended.
