HTTP response code for "Wait a bit"

What is the best HTTP response code for the server being sent if it wants the client to wait a little while, then try again?

Now I am using:

409 Conflict

But this is not entirely correct ...

Depending on why you want them to wait, the status codes will be different. Codes starting with 4 indicate client errors. If the request was executed correctly, I would not use the 400 code. Statuses starting with 5 refer to server errors. If you ask the HTTP requestor to wait due to problems on your side, I would go with 503.

503 + "retry-after", HTTP RFC - https://tools.ietf.org/html/rfc2616#section-10.5.4.
