Your electric current site origin does not match your settings in the OneSignal Dashboard. See Incorrect Site Url Error.

The OneSignal web SDK tin can merely be initialized once. You added the OneSignal init code twice, usually if you accept our WordPress plugin and added code directly. See OneSignal Initialized Twice.

The OneSignal Service Worker files are being redirected but should be in the root directory and accessible. Run into CDN and Redirects.

The OneSignal Service worker files OneSignalSDKWorker.js and OneSignalSDKUpdaterWorker.js must be transferred with the MIME content-type awarding/javascript.

This error simply comes up when selecting the iPad or iPhone view in Chrome's dev tools which mocks the navigator.userAgent string to an iOS device, however it does not mock window.safari so this mistake occurs in that testing environment.

On a real iOS device in either the Chrome or Safari browser this error does not occur. No javascript errors come on a real iOS device.

After you try subscribing to your site, if you see a 403 or 404 error in your Browser Console and/or in your onesignal.com Dashboard > Audience > All Users page, that means something is blocking the OneSignal Service Worker files from being publicly attainable.

It cannot exist served past a CDN or a redirect or a domain other than the domain the visitor is currently on. See the Same Origin Policy Guide for more than details on this browser restriction.

WordPress Plugin Users see common CDN and Cacheing Plugins to fix this.

Non-WordPress users meet our OneSignal Service Worker FAQ if you cannot add the files to the root directory.

If you are integrating OneSignal into a site with an existing service worker (like a PWA), y'all may take to merge service workers in order for OneSignal to work correctly. Come across OneSignal Service Worker FAQ for more details.

In your browser's evolution tools, get to the Service Workers department (nether "Application" tab in Chrome) and wait for "OneSignalSDKWorker.js" as the source for the service-worker for your domain. Detailed Steps to Reproduce.

If you lot do not meet the OneSignal service worker there, you have not configured OneSignal correctly.
