Proxy request timeout on closing connection

[hellium01]

Jetty version
9.4.20.v20190813
Java version
1.8.0_181
OS type/version
Linux 4.15.0-1065-aws
Question
After we receive success from POST request and trying to terminate the request, we receive timeout constantly for certain requests, can someone who is familiar with Jetty tell us on why would we receive idle timeout closing a connection after receive response?

The response was never received.
The request has been sent, but the server did not reply, and after 30 seconds the client timed out.
