If you are using the Anti-Malware or Web Reputation modules, you may see either a
"Smart Protection Server Disconnected for Smart Scan" or "Smart Protection Server
Disconnected for Web Reputation" error in the Server & Workload Protection console. To fix the error, try the following troubleshooting tips.
Check the error details
Double-click the error message to display more detailed information, including the
URL that the server is trying to contact. The error may include:
- Timeout was reached
- Couldn't resolve hostname
From a command prompt, use nslookup to check whether the DNS name resolves to an IP
address. If the URL doesn't resolve, then there is a DNS issue on the local server.
Use a telnet client to test connectivity to the URL on ports 80 and 443. If you can't
connect, check that all of your firewalls, security groups, etc. are allowing outbound
communication to the URL on those ports.
