I can't download the creative cloup app, or even any app (I tried Ps and Ae) from the website. The process of downloadig starts but then freezes quite early on (3;5% / 18%...). I tried to leave it on for the night and nothing changed.
I have a mac book pro from 2015 and it is fonctionning quite well.
I do have a malware (anysearch; it redirects the web browser to search.anysearch.net and the main damage are unwanted changes of custom browsing settings, privacy issues due to internet activity tracking, search redirects, redundant ads) but I don't think it is the problem...
If not, then try using an alternate network to see if the same error occurs. If Error 116 is occurring on multiple networks, then review the settings for any installed security software. If the error does not occur, on the new network, then you will again want to review https://helpx.adobe.com/enterprise/kb/network-endpoints.html and verify you have access to the servers and ports listed.
