Its the same error as with nginx:
~# openssl s_client -connect 10.10.2.1:443
CONNECTED(00000003)
7571:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown
protocol:s23_clnt.c:607:

This would imply that the problem is on the backend (the apache) side.
But: I can connect to the backend directly (not via nginx) using https
without any problem. So I am not sure about this conclusion.
Hm, it might still be a problem with the backend, but its not that ssl
is not working in general on the backend.

Any hints are appreciated :)
