Hello

Could you do a netstat to check what port Ambari is running on, should be 8080. If it's listening you probably have a firewall policy blocking you somewhere. Check the ambari logs as well to make sure nothing is wrong there.

This can happen. What would be useful to troubleshoot is the output in /var/log/ambari-server/ambari-server.out/.log Could you let us know if you see anything unusual in both files? Most common reason is the connection to the database, but as in your case the UI seems not to come up at all, it could be something different.

Yes, having the logs would help. While network issues could be the primary cause, we should also see if for some reason there is a possibility of deadlock.
