Check whether a domain's DNS provider implements the Domain Connect protocol, read live from the _domainconnect TXT record and the provider's settings endpoint. Reports the provider and whether it offers the synchronous flow (a signed redirect with no token exchanged, the one that works in practice) or only the asynchronous OAuth flow. One-click setup also needs the provider to have synced and enabled the service's template.
