I have a certificate that is configured in IIS in windows server 2012 with ocsp_uri.
When I test the server for oscp stapling there is no response:
openssl s_client -connect example.com:443 -tls1 -tlsextdebug -status OCSP response: no response sent
From the server when I test the access to ocsp responder with:
openssl ocsp -issuer sub.class1.server.ca.pem -cert ssl.crt -text -url http://ocsp.startssl.com/sub/class1/server/ca -header "HOST" "ocsp.startssl.com"
I get a response. (the request need to be http/1.1)
How can I check why the ocsp stapling is not being returned by IIS?
