For those of us deployed in large organisations with indifferent IT departments.
It would be useful in Adobe provided a tool to check which of the (100+?) required Adobe Creative Cloud Network Endpoints were blocked by our firewall.
It is not always clear which endpoint is being blocked.
If Adobe provided a Creative Cloud App or web tool that checked your network and then provided a nice report we could present to the stubborn IT bods (who insist they have whitelisted all 100+ adobe links)

(let not get started on why there have to be so many! Or why therer are regional variations? AWS? but why wasn't this considered and written around appropriately?)
