Hi Davide,Thank you for the reply. I would like to ask about the client key file. According to the netx-duo-secure-tls guide, the client key must also be in DER format. It suggests to convert using the command openssl rsa -inform PEM -in <private key...

Hi Davide,I am having the same question as you in your original post. Can you please elaborate a little bit more of how did you load the CA, client_key and client_cert files into the project so that you can have the pointers to those?Best wishes,Anh
