Im getting a weird error while displaying my thing

what does this mean:
Hmm… We couldn’t reach this Repl
Make sure this Repl has a port open and is ready to receive HTTP traffic.

Also I need it to display the screen of the chromium web browser when you hit run for other users so they dont have to fork it.

Replit Profile:

you may have accidentally deleted an important hidden file

Where is the important file and how can i fix it?

you can’t really fix it and i would be able to tell you what’s missing. just take all your files and import them into a new repl
