Dear Maxim, thanks for your ideas.
I think I have not fully understand this matter, yet ;-) - check if OCSP requests from other clients (e.g., browsers) work; note that openssl's OCSP client will likely fail out of the box; ---> it does not work with openssl on Ubuntu 14.04 LTS (OpenSSL 1.0.1f 6 Jan 2014), openssl on raspberrypi2 (OpenSSL 1.0.2e) and Qualsys ssllabs (https://www.ssllabs.com/ssltest/). I do not get any errors on the other hand in Firefox or Chrome on Windows / Ubuntu / Android browsing to my websites. But I do not know how to do the same OCSP tests with my browsers. - check if the same error occurs on x86 hosts for the same certificate or not; --> I have to try this later, it is not that easy to set up here right now. - try tcpdump'ing traffic between nginx and the OCSP responder to see what happens on the wire. --> I have done it. It is showing some communication when I do the test with openssl, e.g. echo QUIT | openssl s_client -connect www.mydomain.com:443 -status 2> /dev/null | grep -A 17 'OCSP response:' | grep -B 17 'Next Update' Pcap extraction show communication: .... .
