NET+OS naSslNgConnect issue

I’m using a 9210
my task is to open an SSL socket using the NET+OS 752

I get an SSL_STATUS_HANDSHAKE_FAILED
when naSslSetCertVerify is set to SSL_CERTIFICATE_VERIFY_PEER.
The defined NaSslCertVerifyCb_t function is never called.

if set to SSL_CERTIFICATE_VERIFY_NONE the connection is established as expected.

in the naSslCreateCertDb the CA certificate is succesfully added…

any idea?

can you test your connection using OpenSSL on the host side and one of the sample applications like naopenssl client on the target? This combination is proven to work using password or certificate authentication
