asked on

OCSP website to check the certificate status

Hi Guys,

I have configured Issuing CA 1 and Webserver 1
Issuing CA - (CA role, CA Webenrollment role, IIS)
Webserver - (Online responder)

Here my question is When i checked the IIS of webserver it show the website for OCSP running but when i click nothing opens (500 error)

Client request me to setup a website for OCSP to access externally, so any one please advise how can I proceed further.

OCSP website output should be - check the status of certificate with options yes, No, Unknown.

Can anyone guide me..?

You can't access an OCSP server from a Web browser + expect anything useful to come back.

https://community.letsencrypt.org/t/ocsp-requests-via-openssl-not-working/37798 provides information about how to accomplish this related to LetsEncrypt.

You must use the openssl command line program + your domain's cert files + point to the related OCSP server.

Refer to your IIS version of docs for how to do this.

With Apache, this requires a handful of lines added to Apache's global config file. Likely the same for IIS.

Note: It's highly unlikely you'll ever have a reason to run the above openssl command, as OCSP tends to work, if you follow your Web server's OCSP setup instructions.
