SSL related errors when trying to add service worker about pwa-fundamentals HOT 7 OPEN

I am also experiencing some trouble with this. For me, it does not work on Chrome. Interestingly, Chrome marks the certificate as "Invalid", even though it seems valid when you inspect it:

This leads to an error when I try to register the SW:

app-d5c93b203741af8b7e1b.js:2538 DOMException: Failed to register a ServiceWorker for scope ('https://localhost:3000/') with script ('https://localhost:3000/service-worker.js'): An SSL certificate error occurred when fetching the script.

I wonder if this might have something to do with the certificate validity being too long?

Anyway, it does seem to work in Safari, and the SW registration was successful there.

You shouldn't need SSL anymore, as http://localhost is considered a secure domain. I'll take a quick look

Thanks Mike - love all your courses by the way!

@gigamesh do you have any errors in your terminal?

I would try to run the app on http://localhost:3000 by running yarn start or npm start instead of trying to get https working.

At the time we recorded this course there were some nasty chrome bugs that required each student to generate a self-signed certificate, but as far as I can tell they've all been straightened out.

yarn start also results in it running on https -- I can't really make sense of the server code so I wouldn't know what to change. Looks like there is a lot of https stuff happening.

@mike-north I am not sure if this is related but I am going step by step by README.MD but getting Privacy Error on localhost:3000

Certificate is invalid, not trusted.

I tried to delete whole project and do it again and again but not use.

@tymochko you can get around this chrome error by typing thisisunsafe in the browser window. I think maybe chrome changed rules about self-signed certificates?
