Hello All,
While doing Network Connectivity test on my Sophos Web Appliances came back with message "Could not connect to URL categorization service over DNS".
Can anybody advise what could be possible reason.
Thank you
Hi Morris
Would you please check if you have allowed Web Appliance to connect on the ports mentioned in this page? Or you may also check whether DNS is allowed from the upstream devices for Web Appliance.
