Same situation here. The Creative Cloud app when connected to company firewall or VPN never lists any updates available. If I however connect my company laptop to my home netwrok, without going through VPN it does pull down the update list and I can then update it on or off the firewall. Through some digging I found that the issue is related to the swupmf.adobe.com (software update manifest, I am guessing) url being unaccessible. I spoke with our IT group and they need to know all access required by the application to be able to properly investigate the required access.
What protocols are involved in the Adobe Creative Cloud application for authorization, downloads, updates, and manifests?
What URLs are involved in the Adobe Creative Cloud application for authorization, downloads, updates, and manifests?
What ports are involved in the Adobe Creative Cloud application for authorization, downloads, updates, and manifests?
What redirects are involved in the Adobe Creative Cloud application for authorization, downloads, updates, and manifests?
I finally got someone at Adobe to help me. He sent me the info below that I then sent to IT. It all works now.
Please check with you Network Admin if the Port 80 and 443 are open. Also, you need to have access to https://activate.adobe.com and https://lm.licenses.adobe.com. These currently resolve into 18.104.22.168 and 22.214.171.124 respectively.
Also use the following host/port combinations when logging in to the Adobe Creative Cloud Desktop access app with an Adobe ID to download, install and activate the Creative Cloud membership.
- lm.licenses.adobe.com:443 (126.96.36.199)
- ccmdl.adobe.com:80 (188.8.131.52)
- swupmf.adobe.com:80 (184.108.40.206)
- swupdl.adobe.com:80 (220.127.116.11)
Also, confirm with your Network Admin if the network has internet security software like Watch Guard installed. If so Adobe applications should be added to the exceptions list.
I've uninstalled this Cloud Desktop rubbish.
I just wanted to try out Edge Reflow.
That's when the trouble started, because, to get anywhere near close to actually downloading anything from Adobe Cloud, I had to carry out the following installations:
- I had to download Adobe Application Manager afresh (over 60MB if you don't mind) in order to update my previously working copy (it worked yesterday, updating Premiere Pro files, so why didn't it work today, huh?)
- I had to install the Adobe Cloud desktop garbage....which, after a successfull installation, pooped out beautifully, classically informing me there was "no internet connection".
- So I Googled for a solution - because, Dear Idiotic Adobe - I DO have an Internet connection (madness)
- Landed at this page and decided it wasn't worth dicking around any further, especially when the actual solution only works for IT folks.
So much for trying out Edge Reflow.
