Hello,
I’m getting this error when i try to check the configuration. recently i did change my nameservers and i’m using custom nameservers. please kindly check the attached image and help me figure this out
Thank you
Howdy,
Well, you just need to do one of the two things it mentions in the warning.
You would need to add “127.0.0.1” to your list of nameservers if you want to continue using the Virtualmin DNS feature.
Or, if you don’t need the Virtualmin DNS feature, then you can disable the feature in System Settings -> Features and Plugins.
