Solution 1Recommended

Restart Acrobat and Re-authenticate Your Account

Often, temporary network glitches or authentication issues cause Acrobat to stall when connecting to Adobe's signing servers.

Adobe's electronic signature service relies heavily on a stable connection to its cloud servers. If your session token expires or experiences a sync error, the application may freeze while trying to initiate the send protocol. Signing out and back in forces the software to establish a fresh, authenticated connection.

1
Sign out of Adobe

Open Adobe Acrobat, click on your profile icon in the top right corner, and select 'Sign Out'.

2
Restart the application

Close Adobe Acrobat completely. Ensure no background Acrobat processes are running, then reopen the application.

3
Sign back in

Click on 'Sign In' at the top right and enter your Adobe credentials to refresh your session.

4
Retry sending

Open your document and attempt to send it for signature again over a stable internet connection.

Restart Acrobat and Re-authenticate Your Account
Authentication Refreshed: Signing back in refreshes the security token required to access Adobe's cloud signature services, clearing most stalling issues.

Frequently Asked Questions

Why does Adobe Acrobat freeze when I click send for signature?

Acrobat typically freezes during this process due to a lost connection to Adobe's cloud servers, an expired login session token, or a corrupted PDF file that the system cannot process for the web.

Does file size affect the ability to send a PDF for electronic signature?

Yes, exceptionally large PDFs or those containing complex, unflattened layers can cause the signing service to time out or stall. Compressing the PDF before sending often resolves this issue.

Can I send a PDF for signature if my Adobe subscription expired?

No, sending documents for electronic signature requires an active Adobe Acrobat Pro or Adobe Sign subscription. If your account is downgraded to the free tier, the send feature will be disabled or fail to execute.
