Hi.
I've noticed that OCSP stapling was broken by 1.15.4, as you may see below:

This problem was also noticed here:
https://community.centminmod.com/threads/nginx-announce-nginx-1-15-4.15672/page-2#post-67107
There are no messages on nginx error log about any failed attempt to
contact the OCSP stapling server. Should I bisect or do you guys already
have some idea about which commit broke this?
