Using “Azure Relay Hybrid Connection” while sending and receiving messages using the websocket protocol, if there is delay in receiving the response no exception occurred.

But using “Azure Relay Hybrid Connection” when sending and receiving messages using the HTTP protocol, if there is >=60secs delay in receiving the response, exception occurs & exception message says “The request was routed to the listener but the listener did not respond in the required time.” Why??

Since it is HTTP protocol, it can’t be keep the connection open forever like websocket?

In “Azure Relay Hybrid Connection” while using HTTP protocol, by default if request timeouts after 60secs, how to extend the default timeout duration?

Timed-out requests can be retried?
