I recently started forcing HTTPS and non-WWW forms for the URL of my React PWA through the .htaccess file, but this is apparently preventing certain applications (such as pwabuilder.com) from accessing public files of the app, such as its web manifest. That said, there are certain applications, such as Chrome mobile that allow me to access the manifest. How can I make it always accesible?

My .htaccess file is structured like this:

<IfModule mod_rewrite.c> 

  RewriteEngine On

  RewriteCond %{HTTPS} off [OR]

  RewriteCond %{HTTP_HOST} ^www. [NC]

  RewriteRule ^ https://aurora.igloo.ooo%{REQUEST_URI} [L,NE,R=301]

</IfModule>

<IfModule mod_rewrite.c> 

  RewriteEngine On  

  RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]

  RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d

  RewriteRule ^ - [L]



  RewriteRule ^ /index.html [L]

</IfModule>

The file that pwabuilder.com can't access is hosted on https://aurora.igloo.ooo/manifest.json

aurora.igloo.ooo has a strange server and preventing some requests from accessing manifest.json.

First time when I clicked your link, I saw the manifest.json. Then I called the main-page by removing the filepath, clicked back in browser-history to see the manifest again and got this shown (with http-response-code 200):

Looking at it in the network-console it's still getting more confusing but also leads to the source of the error:

It's complaining about missing enabling of javascript, so they make some weird things with javascript and probably some hidden redirect too (else the response code would be 3xx). Perhaps they never want the manifest being accessed from outside and it's not configured properly and can be seen under some conditions.

I don't have a quick solution for your problem but it's quite obvious that some clients can't access the manifest and you've to search for another solution. If you're working for aurora.igloo.ooo you've to speak with the frontend-developers and/or server-admins to change something, else you've to offer your own manifest-file. Also it's possible that they offer a solution for the problem, but for that you've either to have access to some FAQ or knowledge-base or you've to contact the support.

Having read about manifest-files on desktop it would force another user-experience and at least in chrome change the complete window. While that might be cool for some special pages it also could be confusing.

Here are the three links I read about it:

1. https://developers.google.com/web/fundamentals/web-app-manifest/


2. https://developers.google.com/web/fundamentals/app-install-banners/


3. https://developers.google.com/web/progressive-web-apps/desktop

My assumption is that aurora.igloo.ooo never want to break with common browsing experience by showing a special app-window on desktop, therefore they prevent the manifest from loading properly on desktop.

I just read the first time about it, so the technical behavior like I understood it might be wrong or it's not the complete technical background.

At least the impression I got is that on desktop it should be considered twice if a website shall run as web-app. If you choose this solution nevertheless, you probably need still find more information about it but the links I posted might be a good start and offer still further details and links.

Another reason to decide against a web-app for desktop might be the compatibility between browsers, as support of technical options is very differing:
