some DNS names were blocked

Duff11

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?

Country blocking is disabled.

.

Thanks in advance.

Regards,

Duff11

    Thanks, I tried it without to configure the two sections request routing and reverse dns.

    I am able to resolve the requested DNS via nslookup. If I try to reach it in a browser, I still get a timeout. :(

    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.
