I’m using the DNS g-e.dedyn.io which is renews from CLI with curl
But today, the domain is gone because “We noticed that the DNS information of the above domain(s) have not received any updates for more than 6 months.”
When I clic on the link to retain it, I get this error “This user does not exist.”
First, let me note that we send two warnings (4 weeks and 1 week ahead) before deleting any .dedyn.io domains. In each message, there is a link you can click to prevent deletion.
You can simply sign up again for a new account, and recreate the domain there.
