Hi. This file will be fetched by users who have opted-in to notifications from your website by their browser from time to time. This is due to how browsers implement support for Web Push using a technology called Service Workers.
You can learn about Service Workers, and how the Service Worker lifecycle may cause this file to be fetched from your server from time to time even if you remove it or if users have not visited your website in a while: https://developers.google.com/web/fundamentals/primers/service-workers/lifecycle
You can replace this file with a blank file or modify how your redirection behavior works in order to avoid seeing the problem you’re experiencing.
Another option would be to add the following code to your website:
navigator.serviceWorker.getRegistrations().then(function(registrations) {
for(let registration of registrations) {
registration.unregister()
} })
The above code will unregister the record of the service worker from users when they next visit your website (if they had previously opted into notifications).
All that said, normally you don’t need to worry about this and it will resolve itself over time.
