Refresh Your Desktop Application Authentication
Logging out and back into the Acrobat desktop app is the most effective way to resolve temporary connection glitches with Adobe's API servers.
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.
Open the Adobe Acrobat desktop application, click on your Profile icon or the Help menu, and select 'Sign Out'.
Close Adobe Acrobat completely to ensure all background processes stop.
Reopen Acrobat, sign back in with your Adobe credentials, and attempt to use the Request Signature feature again.

Send via Adobe Document Cloud Web
Bypass the desktop application entirely by using the Adobe Document Cloud website to send your document for signatures.
Verify Identity Preferences in Acrobat
Missing or incomplete identity information in Acrobat's internal settings can sometimes trigger API errors during the signature process.
