Running this implemnetaion on Tomcat Spring Application throws java.net.ConnectException

[KDPandit]

When I run InstallCert.java file as Java main Application, I am able to successfully run and get the certificate from my server without any issue. But running it in a Spring Application on tomcat, throws down below error. (Pasting only the root cause.)

This failure is seen when the SSLSocketFactory object tries to create the socket.

socket = (SSLSocket) factory.createSocket(host, port);

I am unable to figure out what is causing the issue.

Sorry, the issue was with the port on the server, able to get it working.

Great tool! Thanks
