Machine agent - RegistrationTask - Encountered error during registration.

[Dhinagar.Devapalan]

We have recently tried installing Machine Agent on Azure linux machine. Using Linuz Zip bundle

Linux Install Using ZIP with Bundled JRE (appdynamics.com)

Installation is successful,  Appd machine agent Service is running & active at the OS End, but noticed that the registration request was failed

yyyyyyyy000==> [system-thread-0] 29 Aug 2024 16:33:08,128 INFO ApacheClientImpl - Sending registration request: POST https://xxxxxxx.saas.appdynamics.com:443/controller/sim/v2/agent/machines HTTP/1.1
yyyyyyyy000==> [system-thread-0] 29 Aug 2024 16:33:08,193 ERROR ManagedHttpClient - Request failed with exception
javax.net.ssl.SSLHandshakeException: Remote host terminated the handshake

From the Server, we are able to reach the SAAS endpoint,, without any proxy and default SSL enabled settings is activated, no certificated manually imported on either side.

Any direction on this issue, please
