No DNS on 3CX after automtaic Update on 16.0.4

[avenio]

Hi,

since the automatic Update last night the 3cx will no longer resolve the DNS entries. I can only get the Trunk up if i use the IP insted of the Domain Name!

I have a static IP but the Firewall check will chekc all stun.xyz Servers !

Nothing changened on the backend and it ran the last months!

Thanks

Helge

At the Moment i cant even connect to the 3cx - i am in the morning back in the Office but i tried to ping several Domain names with no success! Nothing Changed :-(

Umm.. if you can't resolve DNS from your computer (and it's not the 3CX server) then it has nothing to do with 3CX.

No, i cant resolve anything from 3cx but everything from all others!

3CX is an application, the operating system is responsible for networking. That's like saying I updated Adobe or Office and now my DNS doesn't work. There's clearly a network issue at play here but we can't really any more help unless you provide more information like so:
