 ### Cause
 
-This issue can happen for the following reasons:
-
-- You have created too many Serverless Functions namespaces and reached [your account's quota](/identity-and-access-management/organizations-and-projects/additional-content/organization-quotas/#serverless-functions).
-
-- You have created too many Registry namespaces and reached [your account's quota](/identity-and-access-management/organizations-and-projects/additional-content/organization-quotas/#container-registry).
+[Private](/serverless/functions/concepts/#privacy-policy) functions require a `X-Auth-Token` HTTP header when being run or tested.
 
 ### Possible solutions
 
-Make sure that you have not exceeded the maximum number of allowed namespaces with the [Scaleway console](https://console.scaleway.com/) or with the [API](https://www.scaleway.com/en/developers/api/serverless-functions/#path-namespaces-list-all-your-namespaces).
+Make sure that you have [created an authentication token](/serverless/functions/how-to/create-auth-token-from-console/) from the Scaleway console, and passed it as a HTTP header while [testing your function](/serverless/functions/how-to/test-a-function).
