Cloudshell web preview 400 error

When previewing the running node or nodemon server with either the 8080 /8081 ports i get only a timeout. Do i need to open the ports anywhere else in order for the preview to work?


do you see any useful info in the developer tools ? Are you running incognito ?

when you run nodemon, please click(server running) at or and check the results.

Lab directions worked well for me. No port have to be opened or changed for node.js app.
Make sure to click "Web Preview" on top right corner of Cloud Shell and not call the localhost URL ( direct from browser.
