I am currently trying trying to learn Redux from a course, it had some provided source code to work from and start the dev env from there. I had quite a few vulenerabilities after running npm i. Tried running npm audit fix --force as suggested in the terminal with no succes. After starting the dev env and trying to connect to localhost:9000, it doesnt let me connect to it. Any suggestions?
