Hello Matt.
I doubt that your example in post #38865 has really worked, since according to the documentation (doc. 4114680, rev. 14.1, page 570) user should provide the certificate in DER format (which is binary) whereas the certificate you provided (in the attached .zip archive) is in PEM format.
I’d like to know what is wrong, if it’s your example or the module documentation, because my company has absolute need to use the HTTPS with server authentication and we choose that module because documentation says it’s supported.
Kind regards,
Peppe
