Hello, your IP address is not banned.
This may be an ISP (internet service provider) side problem, not the z3x server. Wait until your provider update / restart the server, or you can inform your ISP about it.
Try to use another computer and another provider.
May need to check your firewall settings, gateway settings, etc.
You can try to connect via VPN.
Also, make sure that the drivers are installed correctly and the card is connected.
