You should avoid asking additional questions on an existing post that already has an accepted solution.  If the accepted solution does not resolve your issue that you may be having a different problem.  

You would get better visibility and a help if you were to start a new question.

That being said, if you are having a "javax.net.ssl.SSLHandshakeException", you issue is during client authentication and have not even the point of verifying client authorization.  So you need to take a closer look at the keystores and truststores you have setup on both your NiFi and NiFi-Registry to make sure that a mutual TLS handshake can be successfully negotiated.

Feel free to ping me if you start a new community question.

Hope this helps,

Matt

Hi,

I have encountered the same issue and it got resolved by the following steps

Please check the port of Nifi in Ambari UI for SSL and without SSL.

Update similar port within NIFI Settings > Controler settings > REGISTRY CLIENTS with the hostname of the nifi registry.

Then add the proxy user as mentioned in the following link.

Thanks
