Online Licensing Firewall Rule

Hi,
all of our computers are offline by default. In order to use online licensing, I would add a rule to our firewall so that our license server is able to talk to the Chaosgroup online license server.
Which IP Range and / or FQDN need to be reachable by our license server?

Cheers, Florian

Our V-Ray license server application is using the following address and port to connect to our back-end licensing server:
https://ols.chaosgroup.com
and port 443

Make sure that the latest version of V-Ray license server 5.1.2 is installed and you allowed this application and port 30304 into your antivirus and firewall software on the machine where the installation is completed.

Let me know if you need more information.
