Domain mapping and redirect problem


I use your Domain Mapping plugin, but something wrong... :slight_frown:
I have 3 domains, and a subdomain
I would like to use for 'main' domain. It's work, so if I type this url, I can see the webstie. But if I type I see just an error message. The rederict is not work, but why?

On my network I have Clublaplage site with external URL:
The Domain Mappig plugin's Mapped Domains tab is empty

Maybe something is missing from zone for axemple an 'A' record?

Best regards
