Hi Jan,
The problem is due to the mis-matched version between openssl library (used by
application) and openssl executable. Basically the CA/Intermediate CA
certificate hash is calculated different between two versions.
Thank you for your help!

what happens if you run
openssl verify -CApath <dir> client.crt
? is that certificate correctly verified?
