I scanned from my computer at home, not another cloud instance. I was able to connect to port 554 and 7070 with telnet, but could not do anything else. The host closed the connection shortly after. > When you do a "netstat -aln" from your instance, do you see that it is > listening on 443? According to netstat, dhclient3 and sshd are the only two services running, there are no services listening on 554/7070, and tcpdump shows 0 packets to port 554/7070. I'm running into [1], but I have not been able to figure out why this is happening.
