Blocking port 80 and 443 allow Gdrive IP address

[The KrazZzy]

Hello, I am using cPanel and csf installed in it. I have blocked port 80 and 443. Now some of the services are not working. So, If I enable those IPs then it is working fine. Like on my wordpress website Akismet was not connecting after blocking the Ports. So I have allowed Akismet IPs and now it is working.
I have added gdrive backup system on my cpanel server for backup. After blocking these ports, backup is not being generated. So, I want to know what are the IPs of gdrive so that I can allow it in csf so that backup will be stored. I found this link in which there are no IPs but some of the domains.

You don't mention if you are blocking these ports inbound or outbound but really these ports should be open both ways. Inbound needs to be open for your own web sites to show up and outbound needs to be open because lots of services rely on being about to download files and data over those ports.

There is no reason that these ports should be closed in either direction.

Yes I know. But after blocking port 80 and 443 sites are opening fine. I want only to allow gdrive in csf. How is it possible?

You'll need to find the IP addresses google uses for their drive platform, if they make them available. This isn't data we have on hand. If you need IP addresses that aren't listed in that documentation from google (you can easily dig for the IPs) you'd need to contact them directly.


Thanks!
