Zymbit Error Client Authentication

Security Module for Raspberry Pi

I am trying to perform the TLS client authentication with the Zymbit key installed on my Raspberry Pi. I have followed the instructions for the TLS authentication with AWS IoT in the documentation and am stuck by this error.

Could anyone help me with this, please

@pappz2323 - Can you verify this is the tutorial that you are trying to follow?
It looks like there is a note on there that the TLS connection does not work with curl 7.74.0. Is that your issue?

Yeah, I tried with the Buster OS and it worked fine.
In the case of Bullseye do we have any different setting, please ??
