Thanks Chris. I' m a little confused by your suggestion.
I am running Forticlient 5.0.9.347.
After a config backup I see the XML value
<update_action>notify_only</update_action>
but in reading the XML comment it seems that this value applies to software updates, while the thing I' m trying to address in this post is the antivirus signature database (unless that is considered a " software update" too). Regardless of the distinction, my system is not just doing a notify_only, but is actively trying to fetch the signatures and failing every time.
Later in the same file I see the XML values
<antivirus>
<enabled>1</enabled>
<signature_expired_notification>0</signature_expired_notification>
which seem related to my problem. Should I simply set enabled to zero here?
Lastly, the file does have some mention of a " fortiproxy" but this does not seem to be related to fetching the signatures, and there isn' t an XML value to allow the proxy URL to be set, so I' m guessing that isn' t it.
