I don't think certificate would make a difference here.

I tried again https://github.com/mperktold/vaadin14-embedded-jetty on an iPad and attached web inspector to the service worker immediately after opening the page. I then checked navigator.onLine value, which was as expected. I toggled network on/off and validated onLine is updated.

I also put wifi off and validated 'you are offline' is shown. When I put wifi on again, the page gets refreshed.

There could be a timing issue of course but I haven't found anything obvious.
Is there a way you could provide a https://vaadin14-embedded-jetty.herokuapp.com/ version that does reproduce the issue for you?

Could you check the value of navigator.onLine in the web page and in the service worker when you are in that case?
