Hi Brent

Thank you for your suggestions.

I installed stunnel version 5.55 on the client test side (where the openssl version OpenSSL 1.1.1c is).

That has solved the problem.

Kind regards and thanks again for your help,

psk_find() and psk_server_callback() are marked NOEXPORT.

You can try whitebox - decompile ctx.c:: psk_server_callback() and/or blackbox - breaking the problem into parts to see what works/fails.

Decomposing the problem into parts :

a) Two differing stunnel versions and a common openssl library.

b) One common stunnel version and two differing openssl libraries.

Try dumping the symbols for ctx.c::psk_find(), ssl_lib.c::SSL_get_ex_data(), and ctx.c:: psk_server_callback().
