Explanation

The BEST explanation for why a penetration tester cannot scan a server that was previously scanned successfully is that the IP address is on the blocklist. Blocklists are used by firewalls and other security measures to restrict access to certain IP addresses or ranges of IP addresses. If an IP address is on the blocklist, it will not be able to be scanned by a penetration tester.
