Creative Cloud Firewall Exception

[IdleJohn]

How do I allow CC through a firewall? I can't find any information anywhere about which programs/ports to allow.

You need to Allow / Whitelist below ports.

Adobe Ports/Host combinations

ccmdl.adobe.com:80

swupmf.adobe.com:80

swupdl.adobe.com:80

Port 80 is HTTP, right? Why would I need to allow this globally?

Also there doesn't seem to be a way to whitelist hostnames in Windows firewall...

And how exactly do I Allow/Whitelist below ports? Is there a step by step tutorial?

May I know whether you are using Office / Corporate network computer ?

If yes , make sure to contact your IT department and add the Adobe ports to Allow/ Whitelist for Network Firewall.

I installed Creative Cloud a few days ago and used it without any issues. For the last two days, I have not been able to access CC. The receive the error "Please check your firewall settings, ensure that the time settings on your computer are correct, and try again."

I turned off my firewall without any success
