I'm a help desk staff member and I assisting helping a large bank of computer users. I've been assigned the task to troubleshoot an error message that I see when launching Adobe Reader DC. The message will keep repeating itself, no matter what I click, therefore Adobe Reader DC is unusable.
This certificate cannot be verified up to a trusted certificate authority.
Issued to: adobe.io
Issued by: <not sure if I can publish this information>
Valid from 7/29/21 to 7/31/22
Around 4-5 years ago, my work did block all ".IO" websites. We had a lot of gamers come in, using .IO sites for online multiplayer gaming and it was causing a massive disruption. Once blocked, the problem largely subsided.
Is the "*.IO" block causing the error message?
Other than trying to figure out how to add exceptions, is there a way to deploy a certificate via our Windows 2016 Server? Clients are on Windows 10. The Server 2016 was updated for Windows 10 policies.
It's possible that's causing issues. When I go to "adobe.io" it redirects to "developer.adobe.com".
You might want to add an exception to your *.io filter to let those requests proceed.
Problem is, is that my immediate boss is telling me that's not possible because it would affect company wide, not just at my building's location.
Is there another way? Yes, I did type in adobe.io from a station that wasn't blocked by .IO sites and was re-directed to developer.adobe.com
Is there a registry key I can change to maybe put in a different address to get the certificate from?
Or is it possible to locally redirect my PC's adobe.io request to another site via some other means? I'm not sure, maybe host file?
Sorry, I don't have answers to these questions. You will need to talk to someone in Adobe about that.
