NoNodeAvailable Exception with TransportClient over NAT

Elastic Stack Elasticsearch
1

I have a TransportClient connecting to a 2 node search cluster over NAT.
The client starts up fine, over time I'm experiencing a
NoNodeAvailableException though.

Are there any configuration changes recommended for clients over NAT. I've
already discovered to turn sniff off, since that hung the launch. I'm
using 0.19.8

Thanks,
Andy

Heres the deal, I start the app and the client connects and works fine.
After a certain amount of time, a search request fails and writes these
logs. It writes disconnect and connect log almost immediately. The next
requests fail.
