Hi all, When I turn OCSP stapling on because of certificate transparency, I'm getting this error message in Firefox (v66.0.5):

An error occurred during a connection to XXX. The OCSP response does not include a status for the certificate being verified. Error code: MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING

Other browsers works fine and also check for OCSP response with openssl looks good: OCSP Response Data:

   OCSP Response Status: successful (0x0)
   Response Type: Basic OCSP Response
   Version: 1 (0x0)
   Responder Id: C = SK, L = Bratislava, serialNumber = NTRSK-35975946, O = Disig a.s., OU = Responder 2_2, CN = OCSP SubCAR2I2 Disig

Any ideas, where should be an issue ? I can turn off ocsp stapling in about:config: security.ssl.enable_ocsp_stapling;false and page works fine then, but site has lot off customers, so this is not relevant solution for me.

Thank you for all your hints...

Cor-el, great!

Thank you, Problem was with as CertID Hash algorithm. Thankfully, I have an option to change this algorithm to SHA1 on my SSL offloader / loadbalancer (F5 Big-IP).

Thank you.

Yes, Server is configured with ocsp stapling. As you can see in output from openssl, it works. Without OCSP stapling would not work other browsers (i.e. Chrome) because of Certificate Transparency.
