Help with RTC and UCR integration

Hi everyone,

I'm trying to integrate Urbancode Release with RTC and this is the third path I go to try solve this problem.
I've follow the tutorials at Knowledge Center and as result I can ping the server correctly but when I check the authorization (that uses a user login and a password) appears the following authentication error:

Caught: java.lang.NullPointerException
java.lang.NullPointerException
at com.urbancode.urelease.plugin.util.BulkClassLoader.getListAllFiles(BulkClassLoader.java:58)
at com.urbancode.urelease.plugin.util.BulkClassLoader.addAllFiles(BulkClassLoader.java:34)
at com.urbancode.urelease.plugin.util.BulkClassLoader$addAllFiles.call(Unknown Source)
at RTCClientCheckConnection.run(RTCClientCheckConnection.groovy:26)

I've ping the RTC server and the connection is okay:
 
After that I reach out for my contact at UCR Support, but they couldn't solve this and they referred me to RTC server support. So, I've opened a ticket but they couldn't help me too and suggest me to look for help here on jazz forum. There is someone who has any idea of how to solve this?


Thanks,
Regiany.
