If yes, then its not getting added instead the preview page is just showing the extra lines prior to the property that you added, only the lines with + sign matters. ... View more

This is much clear now   On server side the request was rejected as the client was initiating non-ssl connection Caused by: org.apache.thrift.transport.TTransportException: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

Can you check in HS2 logs exactly during the timestamp the error "Unable to connect to server: Invalid status 21" was reported on client. The error you notice on server side will give further clues c. Do you have SSL enabled on HS2 ? ... View more
