Cisco Control Hub

Error message	Likely meaning (TL;DR)	Recommended next steps
message":"The request requires a valid access token set in the Authorization request header.","errors":"description":"The request requires a valid access token set in the Authorization request header."	The Cisco Control Hub Webex API request reached Cisco, but it did not include a valid Authorization: Bearer <access_token/> header, or the token was expired/invalid.	Re-authenticate the integration and make sure your app is sending a fresh OAuth access token with the required scopes in the Authorization header; if this is a production integration, use OAuth token refresh rather than a temporary personal token
"The requested resource could not be found." (HTTP 404, ROUTERGW tracking id)	Webex returned 404 for a specific resource — usually a location, floor, or device that was deleted in Control Hub between listing and fetching it. This is NOT an authentication problem (auth issues return 401/403), so re-authenticating usually will not help.	Re-run Test Connection / Sync on the connector from the portal — if the 404 came from a since-deleted resource it will pass. If it keeps failing, verify the locations and devices still exist in Control Hub, then contact support.
