I have created a trust file both ways:
cat www.hellmi.de.pem > www.hellmi.de.trust
cat subca.pem >> www.hellmi.de.trust
cat ca.pem >> www.hellmi.de.trust
or
cat subca.pem > www.hellmi.de.trust
cat ca.pem >> www.hellmi.de.trust
and configured it as ssl_trusted_certificate, this did not help either. How do I create a trusted certificate for a StartCom CA?
This chain looks like this:
StartCom Certification Authority (ca.pem)
StartCom Class 1 Primary Intermediate Server CA (subca.pem)
www.hellmi.de (www.hellmi.de.pem)
