Why OF server does not work if forced to use TLS 1.2 only?

Following is OF v4.1.3 logs when Client is communicating with TLS 1.2 explicitly.
What is missing from server side setting?

I only enabled TLS 1.2 in encryption protocols and used same TLS 1.2 in our client.

Can somebody please guide me?

Openfire will allow you to use all encryption protocols that are provided by the JVM. My first guess is that you’re using an older version of Java to run Openfire, a JVM that simply does not include TLS 1.2.

To see what encryption protocols are made available by the JVM, you can use the Openfire Admin Console.

First, navigate to the “Client Connections Settings” page, and click “Advanced configuration…”

On the page that opens, scroll down. You’ll see a list of encryption protocols, some of which are enabled. If no changes were made manually, this list reflects the defaults as provided by the JVM.

The screenshot above shows what the JVM that was used on that server supports SSLv3, TLSv1, TLSv1.1 and TLSv1.2, but does not enable SSLv3. The values that are shown will differ, based on the JVM and JVM configuration that is used for your instance of Openfire.

Yes, By default same TLS versions mentioned by you are enabled on my OpenFire server.
And still facing the issue.

I’m trying to enforce clients to use only TLS v1.2.

Here is how client behavior is as follows

Nothing is happening beyond this point except Server closes this connection forcefully after certain stipulated timeout period/idle timeout period.

Any help would be appreciated!
