router_apply_failed

HTTP 503 The router did not accept the change

What happened

The router refused to apply the change, or did not answer while applying it. Nothing was changed: the rule set is as it was before the request.

What to do

Repeat the request later with the same idempotency key. If it keeps failing, read the router state and contact support with the request id.

Retrying

The request itself is fine. Repeat it later; after a 5xx use a new idempotency key and read the resource first.
