It is one of the odd Replit issues with SSL. You can try forking your project and see if it helps or restart with a new fork and see if that works.
When you get SSL errors you can usually get to a working page by using the iframe URL. If you inspect the preview (not the full page) and look at the iframe it has a URL you can copy and use.
I forked 3 times and the live app URL didn’t pass the test. How can I find and copy the iframe URL? All I find on the internet is javascript code but I actually want to copy the iframe URL.
