Flask API apps giving ERR_SSL_PROTOCOL_ERROR: "This site can’t provide a secure connection"

Description of the problem (please keep it simple and short): I’m a computer science teacher, and some of my students are getting an error such as the following when building Python Flask apps that call APIs and displaying their project full-screen: “This site can’t provide a secure connection. may-9-databaseapi-website-project.alexakagiwada.repl.co sent an invalid response. ERR_SSL_PROTOCOL_ERROR.” I can make this error go away on a student’s project when I fork it myself, so the error doesn’t seem to be with the code.

Explain what you were trying to do: I would like to have my students’ websites be loaded full screen without this error. The websites load fine in the small preview window, as well as when I fork their projects myself.

What areas or features are involved? Python, Flask, APIs (called with HTTPS), the full-screen window

Thank you for any help or suggestions!!

It seems like a problem with Replit, they already fixed it and are waiting for everything to recover.
It may take a while, so please stay patient.

I’m getting the same error.
