General

I am making a flask app, I am currently only developing the front-end but the web preview never works I always get ✘ Preview failed to start. Does anybody know how to fix this?

Hi @Jquin - are you using the built-in Flask template? Or are you importing your own project?

Thanks,
Kirupa

Did it happen from the very start or did it break after you started doing some development?
