Refresh Your Desktop Application Authentication

This error often occurs when the authentication token between your local desktop application and the Adobe Document Cloud services becomes invalid or out of sync.

1
Sign Out

Open the Adobe Acrobat desktop application, click on your Profile icon or the Help menu, and select 'Sign Out'.

2
Restart the Application

Close Adobe Acrobat completely to ensure all background processes stop.

3
Sign In Again

Reopen Acrobat, sign back in with your Adobe credentials, and attempt to use the Request Signature feature again.
