<Apr 21, 2018 2:33:26 PM> <INFO> <Secure socket listener started on port 5557>
But in console it is inactive:

And in nodemanager.log:
<Apr 21, 2018 3:52:57 PM> <WARNING> <Uncaught exception in server handlerjavax.net.ssl.SSLException: Received fatal alert: certificate_unknown>
javax.net.ssl.SSLException: Received fatal alert: certificate_unknown
<Apr 21, 2018 3:52:57 PM> <WARNING> <I/O error while closing socket connection>

Thanks for help.
