Hey Team, found similar kind of problem reported in XD community, I'd tried but nothing helps.
BTW I'm using mac and I already tried disabling "set date and time automatically", but the problem presist.
For Adobe dc on a windows 10 computer it is C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\adobe.exe And again just blocking it from being scanned in Trend Micro didn't work. it had to be added to the behaviour monitoring exception list in Trend. Hope that helps.
I had a similar experience earlier this week with Sentinal One. Had to do the same type of operation to exclude the process from being scanned. I imagine others with this problem can benefit by working with their AV settings.
Thanks. What will happen if adobe.exe is replaced with a milicious file with the same name?
What worked here (so far) is to uncheck the feature "Enable Protected Mode at startup (Previewe) in Acrobat > Preferences > Security (Enhanced).
Don't know why/how the feature was enabled.
I had the same issue, tried everything from clean reinstall to removing credentials and registry, then I noticed the same issue on a separate computer with different OS, so my final test was to bypass the router and plug and ethernet cable directly from the pc to the modem.. Then it worked!
Something in the router was blocking Adobes access to the verification server I guess..
Same issue with Adobe DC.
Fixed by: Closing out of all Adobe programs, uninstalled Adobe DC. Deleted Adobe keychain references. Reinstalled Adobe DC. Logged back in.
Problem fixed [for now]
