Problem with domain transferring



I have a problem with transferring my domain to CloudFlare.

Using API ( I get:

Date → Mon, 29 Apr 2019 12:44:37 GMT
Content-Type → text/html; charset=utf-8
Transfer-Encoding → chunked
Connection → keep-alive
CF-Ray → 4cf15e49bff0901d-DME
Expect-CT → max-age=604800, report-uri=""
Served-In-Seconds → 0.700
Status → 500 Internal Server Error
Strict-Transport-Security → max-age=15780000; includeSubDomains
X-Request-Id → 9720fd69ca18f4f2c02bee4d0efa9a87
Vary → Accept-Encoding
Server → cloudflare

Using web UI, the list of domains to transfer is not even loaded:

message: "Unable to determine domain class for, 757: unexpected token 
at '<html>
↵<head><title>504 Gateway Time-out</title></head>
↵<body bgcolor="white">
↵<center><h1>504 Gateway Time-out</h1></center>

BTW, yesterday it seemed operational.
Could you help me please with the issue?


I’m facing the same issue in the web browser.

Cant even load domains already transfered.


Probably a temporary glitch. Does it work meanwhile? If not file a support ticket.


I did file one when I post here.

I got a team working on it and for me it’s solved right now.


A bunch of TLDs yesterday were throwing this error, I believe it’s an issue with the registries that run these (notably due to the nginx server token, CF uses cloudflare or cloudflare-nginx as the server token for their own nginx).

These TLDs seem to have had issues (and may still have issues):


Actually yes, it’s working now.
Thanks for helping!
