First off please start a new discussion as this is completely unrelated to the discussion of “Where to buy a domain name for MiaB”.

The error you have shown is related to resolving DNS from your VPS. It may have been a temporary glitch, or may be a problem with the resolver. Is this hosted via OVH? or have you moved on to a different provider?
