After working on getting a new project to work, I found that for some reason I couldn't start my rails server. I kept getting the following error:

HTTP parse error, malformed request: #<Puma::HttpParserError: Invalid HTTP format, parsing fails. Are you trying to open an SSL connection to a non-SSL Puma?>

I was able to solve this problem by clearing my browsing history, cookies and saved images.

Click ... More tools Clear Browsing Data

Delete everything since the beginning of time.

    What is the core issue here though? Clearing files/images didn't work for me. – Alien Oct 08 '21 at 22:12

    @Alien The core issue is that your browser is trying to access to localhost:3000 instead of localhost:3000 cause you surely already try to access to the https one. – Emilien Baudet Jan 25 '22 at 10:02
