cloudflare_zone_not_bound with HTTP 409. Repeating the same request unchanged does not help.
What to do
Configure the project domain first with ‘ohmyhost domain paid plan’ then ‘ohmyhost domain paid apply’, or configure its sender domain with ‘ohmyhost mail setup’. Then request Cloudflare authorization for that domain’s zone. If the steps above do not resolve it, report it with therequest_id from the error.
