I have a java client that opperates with a remote ES database. The same  
client works without any problem in different computers, but It fails in a  
computer that is behind a proxy.  
In that comptuer all the connections to external computers must go through  
that proxy, I just connect to proxy:9300 and it will redirect the  
conneciton to EsServer:9300 (having the real DNS of the EsServer..)  
In this computer the client program connects, and I can retrieve and write  
some data to ES, but after a while, with what it seems to me a random  
pattern, the connection drops. So, my questions are two:  
a: There is a way to restart the connection when in breaks (i thought the  
client was doing it)  
b: there is any parameter I should as to set up in the proxy (i don't  
manage the computer nor the proxy ☹ so ... I can't give you more  
information about it, for the moment.  
The error stack trace says:
