Unable to connect to port 443 while using JDK17 with debian 12 based docker image!

[iAmSKU]

• Bug exists Release Version 1.2.5 ( Master Branch)
• Bug exists in MQTTv3 Client on Snapshot Version 1.2.6-SNAPSHOT (Develop Branch)
• Bug exists in MQTTv5 Client on Snapshot Version 1.2.6-SNAPSHOT (Develop Branch)

Hello,

I am trying to connect my application (which is dockized) with AWS using port 443 using ALPN protocol.

Earlier when I have used JDK8 with Debian 10, there was no issue in the connectivity but recently I have migrated to JDK17 with Debian 12 (due to vulnerability & other requirement), after migration I found application is not able to connect to the MQTT.

When I connect the same application using the port 8883 it does not have any issue.

Please see the below error traces:
