is there problem with kerio content filtering servers??

since approx. [09/Apr/2018 16:56:53] GMT, i see constant authorisation errors ->

[09/Apr/2018 17:32:18] Unable to categorize 'api.cloudmobi.net/' by Kerio Control Web Filter. DNS response 'FAILURE: Invalid authorization' to query '0.api.cloudmobi.net.147d.ko-290156.v3.url.zvelo.com' is invalid.

our content filter has a current/valid license (expires march 2019) - the box is approximately 1 month old. its very problematic. why ???

from the dashboard

[02/Jan/2013 13:45:37] Unable to categorize 'example.com' by Kerio Web Filter. DNS response 'FAILURE: Invalid authorization' to query 'example.com.f836.ko-34554.v3.url.zvelo.com' is invalid.

I've had the same with my main Kerio firewall, but it ended yesterday. The phenomenon started 17/May/2018 22:21:37 CET+1 and ended 23/May/2018 22:21:47 CET+1 according to the Warning log. The error log shows nothing corresponding til these times. The timing of the start and end time, when looking at the time of day they occured, seems a bit odd.

I have had the same problem several times. I do not know if it will have to do with this:
https://manuals.gfi.com/en/kerio/control/content/content-fil tering/slow-internet-connection-with-activated-kerio-webfilt er-1188.html

too many dns request in a short time??

this problem is critical because the categorization used in the contents rules of Content filter not work and the user can access sites that should not.

On what build of Kerio Control does it happen? Did you try to recheck web filter? For me this operation solved warning messages with not authorized to Kerio web filter.

DNS servers of your ISP are limited and not use network offload. It's a best solution to redirect all web filtering request to another public dns servers e.x Cloudflare DNS (1.1.1.1;1.0.0.1).
