What IPs and Ports to whitelist for the Netdata Cloud

What are the IPs and the Ports we need to whitelist in our firewall to be able to access the Netdata Cloud?

It’s best to use the domain name app.netdata.cloud, instead of the IP address. Or if needed you can use DNS to configure your firewalls, and regularly check what our current IP address is.
Regarding the ports, you should open the 443 (HTTPs/ACLK).
