Facing data source connectivity issue in SQLPAD deployed on Amazon EKS

I am facing following issue in SQLPAD deployed on Amazon EKS.

Whenever I am adding new postgres connection using "new connection" option, I am able to test it successfully and save it but I can't see this new added connection in "Manage Connections" option. Also tables and their respective details are not loading in schema section. But when I click on "Refresh Schema" button 3-4 times then tables list with their schema details get populated in same schema section.

I don't Know, why this weird behavior I am facing. Your help will be appreciated.

Note: I am not facing this connection issue in my local.
