router_scale_forbidden
HTTP 409 Routers cannot be resized by plan
What happened
The platform refuses to move a router onto a different plan: a router's size comes from its image and is not adjustable afterwards. A request like this is normally answered earlier as server_type_not_supported (422), which covers cores, memory, disk size and plan together; this code reaches you only when that earlier check does not fire.
What to do
Drop the plan change from the request. Cores, memory and disk size of a router are not adjustable either, so no variation of this request will succeed.
Retrying
Repeating this request will not help.
