This is because Found attaches multiple IPs to your 0298347602938ahdf.us-east-1.aws.found.io hostname. So if you use a TransportClient with ssl on port 9343 and add the first IP you find with client.addTransportAddress(new InetSocketTransportAddress(host, port)), it’ll eventually stop working because it’s stuck with an old, invalid IP. The solution is to lookup all the IPs on the hostname and add them to the TransportClient, then do this every 1-5min (or something less than the DNS TTL). The TransportClient will check for duplicates and reachability, so you should have a stable system now. I wrote a gist for doing this with Spring and Groovy: https://gist.github.com/vaughnd/04350e4c5bf51dedabb8
