bitcoind connection constantly dropping between 2 VPS on the private network

[WindListener]

I've got a site frontend on VPS1 talking to the bicoind on VPS2 over their private network.

Thing is every few minutes it drops the connection for a while. I'm not even sure where to start the troubleshooting so asking here.

Both are ubuntus 14.04 all up to date
firewall is properly set but even with disabled one it's the same
bitcoind is running fine and well connected

What do you mean by "it drops connection for a while"?

How have you connected the two bitcoinds?

I mean the front end (html5/php site) can't talk to bitcoind from time to tme, connection is dropping for some reason.

there is just one bitcoind on the backend, VPS2
