When changing your firewall rules it’s important to not block access to your VPS over port 3389 (RDP).

If you do this by mistake you will lose RDP access to your Windows VPS.

If your VPS has Plesk installed and you didn’t block access to Plesk you can stop the firewall service through Plesk.

Otherwise contact InfoQuest support and we can stop the firewall service on your VPS to allow you to access it by RDP and you can correct the rules.
