I followed all steps: 1. Check the deployment URL: Ensure that the deployment URL you are using is correct and does not contain any typos or incorrect paths. 2. Check deployment existence: Verify that the deployment exists and has not been deleted. You can do this by checking your project dashboard on Vercel. 3. Review deployment logs: If the deployment exists, review the deployment logs to identify any issues that might have caused the deployment to be unavailable. 4. Verify permissions: Ensure you have the necessary permissions to access the deployment. This still does not work. Appreciate help! Pauline P. Narvas (@pawlean) · 2024-08-21 Hi, @byteda! Did you follow the steps in our community post, https://community.vercel.com/t/debugging-404-errors/437? I'm just making sure in case you followed something else? :smile: If so, could you perhaps share your repo with us to take a look and investigate? Pauline P.
