QSslSocket Behaviour Linux vs macOS (possibly LibreSSL incompatibilities?)

Glad it's working now and thanks for the feedback !
Additonal note, I never wrote that this was a curl problem or bug that was affecting your application. Only that the bug report I found could give some additonal clues to look into to fix your problem.
@SGaist Actually the post above may have been a bit premature. Not sure what is going on: I updated 2 machines to Qt 5.12.0.
On my workstation, it is working as intended and described in the previous post.
Since I assumed the issues have been fixed I also updated my Macbook only to find out the failed handshake still occurs.
Currently I am in the process of investigating what is going on - mentioned computers installations are very similar. All I know for now is that the handshake failures occur only on one computer with standard Qt installation.
I suspect the cause is somehow tied to libssl.a/libcrypto.a, perhaps different ssl version or something like that.I'll keep you advised if I find out what's going on

The one problem I can see is that OpenSSL is not used on macOS since a few Qt versions. Qt use the SecureTransport framework from macOS. You can still use OpenSSL though but you have to build Qt yourself for that as well as get a recent version of OpenSSL.

@SGaist I know - I did compile Qt with OpenSSL 1.0.2o a couple of months ago (Qt 5.10.0).
Unfortunately later versions Qt failed to compile using this config - never figured out why; for the lack of time I just went ahead using mentioned custom compiled version.Yesterday I randomly checked if my server compiles/works using 5.12.0 - and to my surprise it did (on my workstation).
It still doesn't on the Macbook what puzzles me...otool -L indicates everything is similar. The binary compiled on the workstation also does not work on the notebook - so clearly some dynamically linked library causing this. If only I knew which one

Any difference of macOS versions ?
Any hint from the logs on the system ?
Just in case, IIRC, since 5.10 Qt supports also OpenSSL 1.1

OpenSSL 1.1 requires a different backend. The 1.1 release broke API and ABI compatibility with the 1.0 release, hence you have to do a specific build of Qt or any library/application using OpenSSL.

@SGaist I did a fresh macOS install using a VM and can confirm the issue is resolved in stock macOS High Sierra using XCode 9.4.1, Command Line Tools 10.1 for High Sierra and standard Qt 5.12.0 installation.
Guess I have to find some path/ssl lib or similar getting in the way on my Macbook, but this should not be any of your concern.
Again, thanks for support.
Issue solved.

Software mysteries... You may have gremlins playing with your machine ;-)
