CB Protection: Blank white page in browser instead of the CB Protection console after re-installation

Environment

  • Cb Protection: 8.0.0.2562 server
  • Windows Server 2012 R2
  • Console was previously installed on server at some point.

Symptoms

  1. Blank white page shows up instead of console
  2. In the Windows Event log (System Log) there are event ids 15300 and 15301

Cause

  • The problem occurs because of a legacy SSL certificate hash property interfering with the current SSL binding, resulting in the correct binding being deleted. Ran the following cmd to confirm:

    netsh http show sslcert

Resolution

  1. Open MMC Certificate Snap-in and export a copy of the current valid certificate. Save it to the desktop as a backup.
  2. Run the following cmd to delete the certificate binding for port 443:
  3. netsh.exe http delete sslcert ipport=0.0.0.0:443
  4. Re-run the cmd to validate the cert is no longer bound:
  5. netsh http show sslcert
    (Note: You should no longer have an entry for 0.0.0.0:443)
  6. Open IIS > Click on the Website name > Click on 'Bindings' in the right hand column
  7. Choose HTTPS 443 > Click 'Edit' > Choose the CB Protection cert that we want to use for the site.(Note: If the certificate is not in the list, then re-import it from the backup we made on the desktop.)
  8. Once the cert is bound to the HTTPS port again, please restart the CB Protection services and IIS service. Then attempt to connect to the console and let me know if the page is able to be displayed.
