Adobe Acrobat freezing (http://ocsp.digicert.com.....)

Report · Jan 15, 2025

I've recently purchased a plan for my business since I use Adobe Acrobat a lot.

My current version is: Continuous release Version 2024.005.20320 64 bit

My problem is:

Whenever I open a PDF it will open successfully, but soon after I will get a message...

"contacting http://ocsp.digicert.com for ISCP based revocation checking, press ESC to cancel"

Whether I let it continue until the process seems to have completed or whether I cancel the

result is the same - everything on the Adobe Acrobat open screen freezes up. I have to go to

Windows and close the window and restart from scratch.

The result is I am currently paying for the full Adobe Creative / Acrobat and yet using "iLovePDF"

online to work with my documents. I have tried repairing the initial install and still have the same

issue, should I cancel my plan??? What's wrong with this picture???????? and more to the point what the he!! is to be done to correct this huge inconvenience and quickly!!!

Hi,

I hope you're doing well, and we apologize for the trouble.

Are you encountering this issue with a specific PDF file or with all PDFs? The message you shared indicates that the PDF contains a digital signature, and Acrobat is attempting to connect to the server to validate it. Please try allowing Acrobat to verify the digital signature in the PDF. This is an automatic authentication process that connects to a government website to validate the signature.

If the issue is specific to one PDF file, could you share the file with us via direct/private message for further investigation?

For testing purposes, you can also try disabling the Enhanced Security feature in Acrobat and check if the error persists. To do this:

Navigate to Menu > Preferences > Security (Enhanced).
Uncheck Enable Enhanced Security and Enable Protected Mode at startup.
Click OK and restart the app.

For more details, you can refer to this article: Protected Mode Troubleshooting.

Note: Please ensure to re-enable both security settings after testing.

Let us know how it goes.

Thanks,
Anand Sri.
