How to setup internal virtual server and get TLS 1.3 keys from external virtual server via sideband?

Hi, 
I am now able to see traffic being forwarded to internal virtual server when I removed and added new internal virtual server with default config and profile as tcp. If I change profile to http it is not working.

I am also seeing that internal virtual server is sending traffic to its pool node but currently over http port as tcp data and it is receiving Unauthorized error from node as it needs authentication.

Next step is how can we set authentication parameters to internal virtual server or pool node, such that it can authenticate and send data to node via http?
