Page becomes unreachable after a period of time

[luisalguien]

I've been working on an app which uses the default service-worker but after sometime if the page is left open it will stop working showing a "Page unreachable" error until you do a hard refresh, close the tab and open a new one or until you clear the service worker cache. I've got Okta authentication implemented on my app, and when this happens I get the following error:

"Access to fetch at 'MyOktaAuthURL' (redirected from 'MySiteURL/index.html?WB_REVISION=xxxx') from origin 'MysiteUrl' has been blocked by CORS policy"

And the following error comes from the service-worker script: "Uncaught (in promise) TypeError: Failed to fetch"
Had anyone had a problem like this before?

Thanks!

I don't know if it is related, but the CRA 4 does not provide any more service worker, you need to add it manually or use the CRA template. You can do this like here:

#10032

@a-tonchev I'm not sure which CRA version was used to create this project, but the service worker do generates and I can see it on my app, and on the console I can see errors coming from it.
