I'm new to Cloudstack and I started to set up my first cluster yesterday. Everything has been running smoothly until I went to add a new host. I followed the steps on the guide on installing a new hypervisor host and attempted to add it via the UI. When attempting to add, Cloudstack UI comes up with the error "Unable to add host" with no further information. I checked the logs on the host server and seen that it is SSH'ing in and then drops 3-6 seconds later.

Nov 19 17:21:13 pl-c-node-01 sshd[14625]: Accepted password for root from IP_REMOVED port 45410 ssh2
Nov 19 17:21:13 pl-c-node-01 sshd[14625]: pam_unix(sshd:session): session opened for user root by (uid=0)
Nov 19 17:21:19 pl-c-node-01 sshd[14625]: Received disconnect from *IP_REMOVED*: 11: Closed due to user request.

How can I troubleshoot this problem?
