Does "scannable" really mean scannable?

Hi all - I'm pretty new to the Qualys scanner and hope you can help with this question. We used Qualys to map a dozen of hosts through ICMP TCP/UDP on port 21/22/111. These hosts were considered "scannable". However, when we did the actual scan, Qualys returned errors like hosts not found or hosts unreachable. We're pretty sure that there's no firewall rules to restrict access. I don't know what else we can do right now.


Any advice would be much appreciated!
