Restart, Update, and Reinstall Adobe Acrobat DC

Click the Apple menu in the top left corner of your screen and choose 'Restart' to clear out temporary system cache and networking states.

Frequently Asked Questions
Why does Acrobat DC say it cannot connect to Adobe's server?

Will other Creative Cloud apps work if Acrobat DC fails to verify identity?
Yes, it is common for other Creative Cloud applications to function normally while Acrobat DC experiences specific installation or licensing conflicts, as it utilizes a slightly different validation process.
