Web app doesn't work on chrome for android (and 403 forbidden error for manifest.json)

The app works fine on my laptop. After logging in on my phone I see a blank page. The only error I get is “403 forbidden” for the manifest.json file. The app is deployed on an nginx server. I used npm run ionic:build --prod --release to build it. Any ideas what could be wrong? I dont get the 403 forbidden error on my laptop. The permissions for manifest.json are set to -rw------- The directory permissions are set to drwxr-sr-x

Had to chmod 755 manifest.json Didnt work the first couple of times I tried it though
