# Support and recovery Start by asking the agent to run Enhance diagnostics. It reports runtime version, API reachability, and whether a local credential exists—never the credential or its machine path. | Failure | Recovery | | --- | --- | | Not authenticated | Start Enhance browser sign-in and complete consent. | | Plugin unavailable | Reinstall or refresh Enhance through the provider's plugin manager. | | Update required | Upgrade the user-scoped plugin, restart the agent session, and re-check status. | | API timeout or rate limit | Keep the current state, follow the bounded retry guidance, and read back ambiguous writes before retrying. | | Missing build directory | Select the intended local build; the agent must not guess. | | Upload interrupted | Retry the same immutable artifact after connectivity returns. | For help from the Enhance team, email **support@enhancelabs.ai** with the diagnostic status and failing workflow. Do not send credentials, signed URLs, customer canvas content, or local paths.
