Jdbc importer not working to transfer to cloud elastic

[pkyt]

We are experiencing an issue with communication between our program and elastic-search cloud server.

We are unable to establish connection to cloud system. This is due to a failed request of getting a node info, which disconnecting our program from server. (Exception #1). This results in an error that causes our program to fail. This error is due to availability of nodes. (Exception #2)

Exception #1: NodeDisconnectedException

[INFO][org.elasticsearch.org.xbib.elasticsearch.helper.client.TransportClient][pool-3-thread-1] [importer] failed to get node info for {#transport#-1}{50.16.191.15}{49a470021ebdb61e456ccae825b9adcd.us-east-1.aws.found.io/50.16.191.15:9343}, disconnecting...

Exception #2: NoNodeAvailableException

We are wondering how to fix the problem, how to establish a valid connection to the cloud server through using jdbc importer?

Did it work before? Or is it the first try?

If you get "failed to get node info", you are using probably Elasticsearch versions that do not match.
