Starting last night one of the UTM devices we manage started sending us notifications of Spam Filter cannot query database servers
The spam filter daemon is unable to reach the database servers via HTTP. Please make sure that the device is able to send HTTP (TCP port 80) requests to the Internet. You may have to allow such traffic on upstream devices.
System Uptime : 1 day 2 hours 22 minutes
System Load : 0.20
System Version : Sophos UTM 9.411-3
Please refer to the manual for detailed instructions.
It has traffic allowed on port 80 and there have been no changes in over a few months to the firewall so I'm not sure why this started last night.
