    Hi Kevin_Stewart

    The configuration I'm using in my SSLo involves decrypting HTTPS traffic, forwarding it to an explicit proxy (McAfee Web Gateway) for security inspection, and then re-encrypting it.

    Enabling the ProxyALPN option allowed me to use the desired ChatGPT. However, all the traffic using HTTP/2 to communicate ceased flowing to the explicit proxy on the SSLo service chain side.

    Is there a way to resolve this issue and restore the flow of traffic using HTTP/2 to the explicit proxy within the SSLo service chain?

      HTTP/2 to an inline HTTP inspection device is not supported.
