Fix localhost cant provide a secure connection I accidently configured  a web-app to force a secure connection i.e. https, and although I have turned this off, I cannot get chrome to forget this error, so whenever I ask for the url of my local development server;

 http://localhost:3000/


Chrome instead returns

https://localhost:3000/


and gives the error

This site can’t provide a secure connection


I have tried Chrome/Clear Browsing data and this does not help.  The app uses ruby on rails and the secure connection was done by setting   config.force_ssl = true.

How do I fix this?
I always find adding a fake query string after the URL refreshes the cache for me.

e.g. http://localhost:3000/?fake=true
