Hi,  
One of our customer procured the SSL certificate from Let’s encrypt. They configured the certificate in pfx format on server end which is a server application hosted on embedded-apache-tomcat server. And our client applications are running on Android as well as in Web using node js and express js frameworks.

Https communication between server and web client is going through successfully without any problem.

Intermedicate certificate Lets Encrypt Authority X3 is installed on the Android device before initiating the Https communication. But it fails in Android client with the below error.

06-02 12:11:33.192 4882 4988 W System.err: Suppressed: javax.net.ssl.SSLHandshakeException: Handshake failed

Any help on this would be greatly appreciated.

Thanks

I think this line is what you wanted.  
Googling the whole line will show you a stackoverflow post, [android - Javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: Failure in SSL library, usually a protocol error - Stack Overflow](https://stackoverflow.com/a/30302235).  
Hope this helps.
