+## Problem
+You are unable to push images to Scaleway's Container Registry.
+
+### Symptoms
+- The `docker push` command fails with an error message.
+- Authentication or authorization errors occur.
+- The image push process hangs or times out.
+
+## Possible causes
+- Incorrect authentication or authorization settings.
+- Misconfigured or outdated Docker client.
+- Network connectivity issues or firewall restrictions.
+- Exceeded Container Registry quotas or limits.
+
+## Solutions
+
+### Verify authentication and authorization
+- Ensure you are logged in with a valid Scaleway account using `docker login`.
+- Confirm that your account has the necessary permissions to push images.
+- Verify that your Docker client is [correctly configured](/container-registry/how-to/connect-docker-cli/) for Scaleway's Container Registry.
+
+### Review error messages and logs
+- Run the push command with verbose output for more details:
+  ```sh
+  docker push --debug <your-image>
+  ```
+- Check the Docker client logs for warnings or errors:
+  ```sh
+  docker logs <container_id>
+  ```
+- Verify Scaleway’s Container Registry [status](https://status.scaleway.com/) for any ongoing incidents.
+
+### Check Docker configuration and version
+- Ensure your Docker client is up-to-date by running:
+  ```sh
+  docker --version
+  ```
+- Check for configuration errors in the Docker daemon and client.
+- Review the [Docker documentation](https://docs.docker.com/) for known compatibility issues.
+
+### Investigate network connectivity issues
+- Confirm that your internet connection is stable.
+- Check firewall or proxy settings that may be blocking the connection.
+- Try pushing the image from a different network or VPN to rule out local issues.
+
+### Verify Container Registry quotas and limits
+- Ensure you have not exceeded your Scaleway Container Registry storage limits.
+- Refer to Scaleway’s documentation for [quota information](/organizations-and-projects/additional-content/organization-quotas/#container-registry).
+
+## Additional troubleshooting steps
+- Try pushing a small test image to verify general functionality:
+  ```sh
+  docker pull alpine && docker tag alpine <your-registry>/test-image && docker push <your-registry>/test-image
+  ```
+- Review Docker’s official [troubleshooting guides](https://docs.docker.com/tags/troubleshooting/) for further insights.
+- If the issue persists, [contact our support team](https://console.scaleway.com/support) with error logs and diagnostic details.
