XG 85 and 105 not resolving specific hostname

Greetings guys,

Hope you all doing well,

I'm running Sophos XG 85 and 105 at:

XG105 (SFOS 17.5.17 MR-17-Build837)

XG85 (SFOS 17.5.17 MR-17-Build837)

I have multiple network environments where I use Sophos Firewalls XG 85 and 105.

When I try to access the site https://vwtbpress.com from a computer plugged behind the Sophos enviroment or directly through the Firewall diagnostics screen all I receive is a message that the network could not resolve it's hostname.

I tried in several networks that does not have a XG and the site works normally.

I asked some partners who I knew use Sophos and they get the same error.

Does anyone ever faced something similar?
