I am working on a requirement where I am using AWS DocumentDB as database and using NodeJS as programming language in backend application and deploying the setup on AWS ECS Fargate. When I configure backend APIs in front end app and executes the backend APIs then it works for initial few calls and then after sometime i get error message as below.(FYI - I have whitelisted the container security group of my backend application in DocumentDB cluster's security group.)

{ "message": "Client network socket disconnected before secure TLS connection was established", "stack": "Error: Client network socket disconnected before secure TLS connection was established\n at connResetException (internal/errors.js:607:14)\n at TLSSocket.onConnectEnd (_tls_wrap.js:1544:19)\n at TLSSocket.emit (events.js:327:22)\n at TLSSocket.EventEmitter.emit (domain.js:467:12)\n at endReadableNT (internal/streams/readable.js:1327:12)\n at processTicksAndRejections (internal/process/task_queues.js:80:21)", "name": "MongoNetworkError" }

Any idea on it's resolution?Any help is appreciated.
