I puchased a code signing certificate and when I try to export a build for Illustrator in Extension Builder 2.1 I get the following error:
Unknown Error (Often Incorrect Timestamp URL)
I am also running into a similar issue with a new cert, although I get the error message even if I don't have the option to time stamp the certificate checked. Is there a place where the export logs to so that I can get more info on what that unknown error might be?
I also get the error message whether the time stamp option is enabled or not. It happens whether I leave the default TSA URL, or whether I change it for Comodo's or any other.
So far I haven't found any way around this, nor have I found export logs.
Should we find a solution around this, I'll post it here. Please let us know if you find a way around it too.
I believe I have found a solution to this. The certificate file (.p12) should contain the whole chain of certificates, and not just your leaf one (a.k.a the one with your name). So in the end, it has nothing to do with the timestamp URL, which is why it happens whther you chose to timestamp your extension or not.
If you are on a Mac, you can follow the instructions in the "final step" on this page: http://scottgaertner.com/code_signing/ to put together your p12 file.
Note that for him this means 3 certificates, but if you have a new Comodo code signing certificate like I do, this is 4 (yours with your company name, "COMODO Code Signing CA 2", "UTN-USERFirst-Object" and "AddTrust External CA Root"). Basically, include the whole chain all the way and including the root certificate.
That's it. I hope this is useful ot others.
