Error while restarting server that was stopped [{response.st

Error message

Error while restarting server that was stopped [{response.status_code}: {response.json}].

What it means

Raised when restarting a server that was in 'stopped' state: the module calls the action endpoint (effectively 'power on') and the API returns a non-2xx response. Status code and JSON error body are embedded in the message.

Solutions

Inspect the embedded status code and response.json for the exact cause
Ensure the instance exists and is not being deleted
Retry the play after a short wait; Scaleway state transitions are async

Defensive patterns

Strategy: retry

Try / catch

- name: Restart stopped server
  scaleway_compute:
    state: restarted
  register: r
  retries: 3
  delay: 15
  until: not r.failed

Prevention

Ensure the instance is fully provisioned before restart tasks
Keep tokens scoped and valid for compute actions

When it happens

Trigger: restart_strategy finds fetch_state(...) == 'stopped' and calls restart_server(); the Scaleway API rejects the action (401/403/404 or server in an unstable state).

Common situations: Powering on an instance that is mid-deletion, token lacking compute permissions, or API transient failure.
