I installed the Cumulocity Linux Agent on my Rapsberry PI, but I'm not able to register them on the Cumulocity platform. The platform stay in status Waiting for connection". To find out whats wrong I started the Cumulocity agent in Debug mode and found the following snip after the initializing the driver list: 

"java.net ConnectionException: Verbindungsaufbau abgelehnt"

When take a look with nslookup anything looks fine. I've also switched off my firewall to check it out. Has anyone any idea whats wrong? I've currently no connected sensors to my Pi.

I have been having an issue with the Rasberry pi agent too. Details at https://support.cumulocity.com/hc/en-us/articles/206926707-Ask-developer-questions-on-stackoverflow-com

The agent is unable to locate the path to JAVA_HOME and I think that spans off related issues .Pl there is not enough documentation on the configuration file

Check /usr/share/cumulocity-rpi-agent/cfg/cumulocity.properties file and uncomment the host and add your hostname
