Hi @Ishant_Srivastava,

Welcome to MongoDB Community.

Please verify that your public bundle TLS certificates on this host are up to date.

See my repsonse for Java issue and try to use it for your use case:

Issues connecting to Atlas Database

Hi @Excel8392, Atlas requires this certificate for the SSL encryption. For latest Java runtime it should be present in the key store, but I suspect you are using an older version: Let’s Encrypt isn’t present in the default trust store for Java version 7 prior to the 7u111 update, or Java version 8 prior to the 8u101 update. Use a Java release after 19 July 2016. Please ensure your Java client software is up-to-date. The latest Java versions are strongly recommended for many improvements bey…

If you can also test a mongo shell connection from the same host it will be great.

Best regards,
Pavel
