I ran https://amarclassonline.com through PWABuilder, but it looks like you're missing both a manifest and a service worker. Is that correct?

The manifest & PWA is there on https://amarclassonline.com/classroom/ pointing to https://amarclassonline.com/wp-content/uploads/icon-512x512.png for the 512x512 which I can load from the browser but no SW indeed.

[MrVibe]

Nope, you have to visit the link : https://amarclassonline.com/classroom/ , for the service worker to get active on the site. USe the url : https://amarclassonline.com/classroom/ for generating the app and you'll see

the manifest is generated : https://amarclassonline.com/manifest.json and the service worker is this : https://amarclassonline.com/firebase-messaging-sw.js?v=1.5.1.0

Hi @MrVibe,

The issue is that your web server is blocking access to PWABuilder's Android dev tools. Specifically, the follow URL instructs our dev tools to download your 512x512 image. It should return the image. Instead, it's returning 403 Forbidden:

https://pwabuilder-cloudapk.azurewebsites.net/fetch?type=blob&url=https://amarclassonline.com/wp-content/uploads/icon-512x512.png

We had fixed this a week or two ago, but only for errors that were returning CONNECTION REFUSED, which is why you are still hitting the problem. I'm filing a fix for this now.

In the meantime, here's a workaround:

In PWABuilder, when you go to download your Android package, click Options, and change the following values:

• Icon URL: https://pwabuilder-safe-url.azurewebsites.net/api/getsafeurl?url=https://amarclassonline.com/wp-content/uploads/icon-512x512.png
• Manifest URL: https://pwabuilder-safe-url.azurewebsites.net/api/getsafeurl?url=https://amarclassonline.com/manifest.json

Click Done, then click Download. Your Android package will be generated successfully. Give it a try and let us know.

We've got a workaround using the pwabuilder safe url redirect and the fix will be soon deployed to production. Closing the issue. Thanks for helping us improving the project!
