some DNS names were blocked

Hi,

I am using a sophos sg115 with home license (firmware version: 9.709-3).

My problem is that I can't connect to some url's (e.g. subdomain.atlassian.net). If I use the direct connection of my Deutsche Glasfaser account on modem, it works. Also if I use my mobile LTE connection as hotspot. I can't find the issue on the utm but this is the only firewall component between my PC and DG router/modem.

Any ideas?

Webfiltering is disabled.

Country blocking is disabled.

.

Thanks in advance.

Regards,

Duff11

  • Do you use Webfilter (Proxy)? Ah, I see you already wrote this is disabled.

    Are you sure  that your "modem" is a modem and not a router?

    How does it know about the network behind your firewall?

  • After making any DNS changes I would do two things:

    On the client, open a command prompt window and flushDNS at the prompt: ipconfig /flushdns

    On UTM, flush your cache: Network Services > DNS > button at the bottom to flush cache.

    Then try to go to your site after doing those two things.
