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,
