A revoked credential is still in use
Symptom
After you delete or edit a credential, some agents change to Requiere atención (Needs attention) and others keep using the old one. When you try to save a new credential, you may see "El proveedor rechazó las credenciales. Verifica los valores e inténtalo de nuevo" (The provider rejected the credentials. Check the values and try again): Studio validated it with the provider before saving it and the provider rejected it (key copied incorrectly, expired or without permissions).
Cause
Agents and workflows reference the credential by name. When you delete it, the ones that used it are left without a provider. If you edited the secret instead of deleting it, all of them pick it up immediately; if you created a new credential, nobody uses it until you select it or mark it as the default.
How to confirm it
In Administración > Credenciales (Administration > Credentials), check which one is the Por defecto (Default) for that provider. In the affected agent, open its model or tool configuration and look at which credential is selected.
Solution
- To rotate without interruptions, use Editar (Edit) on the existing credential and enter the new secret: it keeps the name and all the references.
- If you already created a new one, mark it with Hacer predeterminada (Make default) and review the agents in Requiere atención one by one.
