I've tried on windows and had same problem.

At the end we figured it out - I was indeed connecting to RSSL port but it expected TLS encryption. Using RSSL_ENCRYPTED channel with a proper keystore did the trick.

Also, note that Java Elektron SDK seems to run without problems even on officially unsupported Ubuntu.

First of all, EMA does't support Ubuntu. Please refer to API Compatibility Matrix for supported operating systems and compilers.

I got the same error if I run an example to connect to TCP port (8101) which is not RSSL protocol. The default TCP port or RSSL is 14002. 8101 is a TCP legacy port for source sink library protocol.

consumer  = EmaFactory.createOmmConsumer(config.host("192.168.27.48:8101").username("user01"));

From the error, the application is connecting to non-RSSL port so it is unable to initialize the channel. Please contact the TR representative who provides you with the server information for confirmation.

You can also share your code or configurations so I can verify it.

Thanks, I try on windows, then contact the TR representative if the problem persists.
