Registrar: "Something went wrong, try again..."

Hi, CloudFlare Registrar services are really nice and uncomplicated.

However, today I was transferring a domain to CloudFlare Registrar: EPP, Contact Info, and at the end there was this message:
“Something went wrong, try again…”

It took me a bit to figure out that the “something” that was wrong was my expired credit card.

It would be nice to have a better error messages, such as:
Domain is locked,
Invalid EPP,
Payment error,
… I do not know what else could go wrong.

Thank you for the great services you provide.

I will be sure to pass on this feedback to the team. Thanks for using Cloudflare products.
