Description

fix: reject clients that do not send a proper payload

Motivation and Context

nodes trying to connect to hosts that do not
trust them must reject with 403's

Currently, there are places where we keep the connection
active and mux server has to reject the connection with
a deadline later.

How to test this PR?

Start with a three-node setup and then expand with 2nd pool by adding 4th node but with the same three hosts from the previous pool with a new drive.

Please don't restart the first pool nodes, only start the second pool. Leads to random
errors showing up in the logs.
