To make sure xCloud can connect with your servers, you need to allow xCloud’s IP addresses (IPv4, IPv6) at your service providers. This is crucial, especially if your provider uses a firewall or has strict API access controls.

For whitelisting xCloud IP addresses, you need to head to your firewall setup and allow xCloud IP addresses to your whitelist.
