HTTP 409 Server state does not allow this operation

What happened

Another operation on this server is already running or is being submitted at this moment - a create, a reinstall, a backup, a disk or plan change, or a second request of your own. The same code answers concurrent operations on one network, including attaching or detaching its router. The request itself is valid; the resource is occupied.

What to do

Wait for the running task to finish, honouring Retry-After when the response carries it, then repeat the same request with the same idempotency key. This is not a failure on our side - that arrives as 503; here the state is what blocks you.

Retrying

Change the state this refers to, then repeat the same request with the same idempotency key.

Branch your code on code, never on the wording of title.
