Troubleshoot Smart Protection Server Disconnected errors

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 Workload Security console.

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
  • Could not resolve hostname

From a command prompt, use nslookup to check whether the DNS name resolves to an IP address. If the URL does not 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 cannot connect, check that all of your firewalls, security groups, and so on are allowing outbound communication to the URL on those ports.
