HTTP 409 The VPN interface on the router does not match the platform records

What happened

The tunnel interface on the router does not match what the platform has on record: it was changed inside the router by hand (the key replaced, a second marked interface added, the subnet changed). Managing devices in that state would hand out configurations that cannot connect.

What to do

Restore the tunnel inside the router to match the platform records, or contact support with the request id. Then repeat the request with the same idempotency key.

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.
