503 with Retry-After |
The sign-in service could not be reached, this panel's sign-in for agents is not completely configured or, on IncubaCloud SaaS, the panel was asleep or restarting: the first call wakes it up and may take up to a minute. Try again shortly; if it lasts, contact support or check the OAuth provider. |

60 sign-ins from your address failed within a minute. Wait a minute and fix the credential: sign in again, or check the API key. |
| Your agents made too many calls in the last minute |
Your agents together passed the per-user limit. Wait a minute; managers can raise it in Settings, Rates. |
| Secrets are changed in the panel |
The agent tried to send a password, key or token: set it in the panel. |
| This confirmation has expired |
More than ten minutes passed, or the approval was for another action: ask for the action again. |

Your client cannot show the question itself: open the link, approve, and ask the agent to try again. |
