You receive an API key alert when attempting to view File Analysis report details, or the  Web 

Security appliance is unable to connect to the AMP Threat Grid server to upload files for analysis. 

This error can occur if you change the hostname of the AMP Threat Grid server and you are 

using a self-signed certificate from the AMP Threat Grid server, as well as possibly under other 
circumstances. To resolve the issue: 

Generate a new certificate from the AMP Threat Grid appliance that has the new hostname. 

Upload the new certificate to the  Web Security appliance. 

Reset the API key on the AMP Threat Grid appliance. For instructions, see the online help on the 
AMP Threat Grid appliance. 

Files are not evaluated or analyzed as expected. There is no alert or obvious error.

The file may have been sent for analysis by another appliance and thus already be present on the File 
Analysis server or in the cache of the appliance that is processing the file.
