Missing staticfiles manifest entry for 'main.css'

I’m trying to publish an app with django but at the time of publishing it gives me the error that does not find main.css I guess the staticfiles, I leave the link to the repository, a part of the error that appears in logs and the link to the page (throws an internal server error)

Link on render:

Hi,

The error sounds like you’re not collecting your static files as part of the build.
