  • I suggest you check the certificate chain you're using.

    I remember having a similar problem and it was becasue the server needs to contact the CRL of the CA that issues the certificate.

    At this moment I am not 100% sure of this, but you can give a try on this idea...

  • Hello!


    I hab the same error.


    And i fixed it right now.


    Your Computer may has too many trusted root certification authorities.


    Maybe this can help you:


    To resolve this issue if the January 2007 update for Microsoft root certificate program members is installed, remove unnecessary trusted root certification authorities. To do this, follow these steps:

    1. Click Start, click Run, type MMC in the Open box, and then press ENTER.
    2. On the File menu, click Add/Remove Snap-in.
    3. In the Add/Remove Snap-in dialog box, click Add.
    4. In the Add Standalone Snap-in dialog box, select Certificates, and then click Add.
    5. In the Certificates snap-in dialog box, select Computer account, and then click Next.
    6. In the Select Computer dialog box, select Local computer, and then click Finish.
    7. In the Add Standalone Snap-in dialog box, click Close.
    8. In the Add/Remove Snap-in dialog box, click OK.
    9. Under Console Root, expand Certificates (Local Computer), expand Trusted Root Certification Authorities, and then click Certificates.

    Delete the certification authorities that are unnecessary.


    Good luck!-)

    How do you know exactly which certificates are un-needed?


    How many cretificates should OCS servers have?


    I had a clean install on VMWare that somehow ended up with 30 certificates!!


    Do I just keep the certificate for the OCS services??
