My web app launches from Render, but the page keeps flashing (redirect)

We had a TypeScript web app, hosted on Render and used Auth0 for integration. It was working for 8 months, but this weekend the developer left. So I relaunched the App from Github onto Render, setup the environment variables, and then deployed it on render. The page shows up, but keeps flashing. I think it is a re-direct. How do I fix it. If my app is deployed on
Is this the same URL that I need to add to the list of CALLBACKS on the Auth0 settings?

Hi @edwardw,

Welcome to the Auth0 Community!

Are you still having issues with this? Can you tell us more about your app? What framework you’re using?
