i have to restart my system at least two times a day because my Creative Cloud App stopps syncing. This affects Creative Cloud Files as well as Fonts from fonts.adobe.com and it’s a massive problem because it interrupts my whole workflow. I’ve tried to restart the app but that won’t solve the problem.
The system is a mid 2015 MacBook Pro and macOS 10.14.5. All Adobe Apps have the latest version.
I have had similar, dunno if this helps you but maybe worth passing it on as I know how much hair I almost taired out trying to solve it!! 😉 I am on a Mid 2010 iMac running IOS High Sierra 10.13.6
Shut down Chrome (if open) Dont really use Safari - could be same issue though? Cant comment on that..
Open System Preferences>Network and select your Wi-Fi (if its wi-fi) top of list
Click the 'Advanced' button then in next window click 'Proxies'
Left hand pane 'Select a Protocol to configure' make sure ALL are deselected. The one that comes back EVERY time I fire-up Chrome is the tick box for 'SOCKS Proxy'
Under that payne, tick the checkbox for 'Exclude simple hostnames'
At the bottom UNCHECK 'Use Passive FTP Mode (PASV)
Click OK then Click 'Apply'
When I have Photoshop or illustrator open in background window where I can see Library is not synced, it IMMEDIATELY begins to load all my Library files after these steps 🙂
Bit of a pain, but it doesn't take long and now, when I don't really need a browser open as I am busy working, I don't leave one running any more in the background. If I need to go online for something, I just follow these steps again. I have an ipad, I have Creative Cloud on there too (which works really well) and I check my email and anything else I need on the ipad by my iMac while working in Photoshop etc on there.
Hope you manage to sort it, sorry if this doesn't help You but it works for me EVERY time! 🙂
