Gitpod cannot resolve workspace image: hostname required on workspace start

I've gitpod selfhosted in EKS. When I try to start a new workspace I have this error:

Request createWorkspace failed with message: 13 INTERNAL: cannot resolve workspace image: hostname required

Unknown Error: { "code": -32603 }

I haven't found any solution. Any idea? Thank you

I run v2022.03.1 and now I have all three DNS records configured. It works.
