It sounds like you're experiencing some connectivity issues with your game launcher. The NAT Type being unchecked and grayed out suggests that there might be an issue with your network configuration, particularly with port forwarding or firewall settings.
To resolve this, you can try the following steps:
Check your firewall settings: Make sure that your firewall is not blocking the game launcher or the game itself. You may need to add exceptions for both the launcher and the game executable.
Port forwarding: Ensure that the necessary ports for the game are forwarded on your router. You can usually find this information on the game's support website or forums.
Router settings: Double-check your router settings to ensure that UPnP (Universal Plug and Play) is enabled. This allows devices on your network to automatically open the necessary ports for online gaming.
Restart your router and PC: Sometimes, simply restarting your router and PC can resolve connectivity issues by refreshing the network connections.
I hope one of these suggestions helps you get back into the game! Let me know if you need further assistance.
