Agent Handler communicating to several machines on port 443

After we updated to ePO 5.10 Update 10 yesterday, our Agent Handlers have started sending traffic over port 443 to the agents. 
Any particular reason it might be doing this?

Re: Agent Handler communicating to several machines on port 443

Hello @akaraj26 

An Agent Handler will be listening on port 443 by default and will receive communication from agents on that port, but your OP suggest the Agent Handler send data over that port to the end nodes which is not correct as those nodes are not listening on that port.

Do you have some evidence of this behaviour or how have you identified this?
