Uhm. That could be. However I think that mixing openssl and libressl
could be an even bigger can of worm, given that they have the same soname.

Ah. There is some kind of hack in squid to get the missing certificates.
but openssl verify checks ok without going to the net (I did a strace to
check the cafile).

libressl seems to be the most probable issue then. Not an easy fix I fear

Thanks for the advice
