Where and how do I change DNS? This also applies to our mobile phones.

Hi @NordloJan,

Thanks for the update. It is happy to hear you are back online now. I connected the VPN to Norway earlier and successfully accessed Nebula Control Center, and also there was no Nebula incident. So we cannot clarify what issue you encountered.
Please help to provide more details if you cannot access Nebula Control Center again. Many thanks.

We still have problems. Can we change the DNS in the router instead so it affects all computers in the network?

Gardis

How is it possible that the DNS affects so that "applications" at the top right of the My Zyxel page are not displayed?
