Can anyone pls help me with Open-Shift Routes?

I have set up a Route with Reencrypt TLS termination. Calls made to the service endpoint (https://openshift-pmi-dev-reencrypt-default.apps.vapidly.os.fyre.ibm.com) results in:

Requests made to the URL does not seem to reach the pods, it is returning a 503 Application not available error. The liberty application is running fine on port 8543, application logs looks clean.

I am unable to identify the root cause of this error, The requests made on external https URLs does not make it to the application pod. Any suggestions on how to get the endpoint url's working?

Thanks for your help in advance!

Openshift version 4.2 Liberty version 19
