Hi Andrija, sadly i can't give you the log with the DEBUG option as i played around a bit more before reading your mail. Nevertheless I uploaded the "last" sequences of the agent.log
https://pastebin.com/jjKPzGqM as well as the management-server log https://pastebin.com/3ht00jyq from the actual time-frame. I was able to join the host at least, as i provided the required "default"-values in the agent.properties manually. At the moment I am a bit puzzled as i just relie on the configuration done by the cloudstack-agent during installation and the installation guide. Same goes for the management-server. So no special configuration or anything done. Thanks in advance!
