+## Problem
+
+I get error messages when testing Serverless Containers using the Scaleway Console.
+
+### Cause
+
+Testing **Private** Serverless Containers is not possible using the Scaleway console due to CORS limitations.
+
+### Possible solutions
+
+- Change the visibility of your function to **public**. Public containers can be executed anonymously.
+
+- Make sure you have created an [authentication token](/serverless/containers/how-to/create-auth-token-from-console/) for your private function, then exexute a `curl` request from a terminal, as shown below:
+    ```sh
+    curl -H "X-Auth-Token: <YOUR_AUTH_TOKEN>" \ <YOUR_CONTAINER_ENDPOINT>
+    ```
