Thanks for a zip containing config files. I am still missing trustStorePassword.
The good thing is that without a valid trustStorePassword I’ve reproduced the same behavior as the one described by You. When I try to connect with https, I get:
Caused by: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
I get an error as my truststore password is invalid. Please check Your password and let me know if this helped.
