Getting "cURL cannot communicate with license server" when installing Plesk in a GCP instance

I’m trying to activate a new Plesk license on a CentOS instance on Google Cloud Platform Compute Engine instance. On the Plesk activation screen, I add my activation code and then receive this error:

cURL cannot communicate with license server https://id-00.kaid.plesk.com:443/ (195.214.233.82): Couldn’t connect to server(7) cURL cannot communicate with license server https://id-00.kaid.plesk.com:443/ (): Couldn’t resolve host name(6) (Error code: 2)

I then followed the instructions at https://support.plesk.com/hc/en-us/articles/115000256834-Cannot-install-Plesk-license-key-WordPress-plugin-or-a-Plesk-extension-cURL-cannot-communicate-with-license-server at the bottom in the GCP area and I created a firewall rule on GCP like this below, but still unable to communicate and activate. I already asked Plesk support and they said it was a firewall issue. Any idea how to solve this?

    Probably your firewall rule is not attached to your instance. Check that your Source Filters is IP range and is set to either your instance IP, the subnetwork of your instance or 0.0.0.0/0 to apply to every instance in your project.
