    Thank you for reaching out. If I understand it correctly you have set-up Mutual Authentication on your application gateway and uploaded the root CA certificate, but the full chain is still not visible.

    Could you please confirm if you have followed the steps mentioned below?

    • As documented here if your client certificate contains a root CA certificate, multiple intermediate CA certificates, and a leaf certificate, make sure that the root CA certificate and all the intermediate CA certificates are uploaded onto Application Gateway in one file. For more information on how to extract a trusted client CA certificate, see how to extract trusted client CA certificates.
    • Can you confirm the root CA certificate is uploaded as a PEM or CER file to the gateway?

    Thank you! Please let me know if you have any questions. Thank you!
