When running the tutorial for substrate-frontend-template in Chrome/macOS, it doesn't load due to a websocket error. The tutorial says to use "yarn start" which invokes: "react-app-rewired start"

Tutorial: https://docs.substrate.io/tutorials/get-started/build-local-blockchain/#:~:text=yarn%20install-,Start%20the%20front%2Dend%20template,-The%20Substrate%20front

where section is "Start the front-end template"

Adding comment from Oliver as answer ( so this question don't stay "unanswered"): You have to make sure that node is still running on same port as you are trying to connect
