--- Comment #41 from simon.bluhm at gmail.com ---
I have not been able to consistently reproduce this and not sure what exactly is causing this but users of my app have reported several "Failed to execute 'transaction' on 'IDBDatabase': The database connection is closing" errors.

To investigate further, I added the IDBDatabase close event to my code and it seems to fire a lot on iOS 13.3.1 but I have also seen it on iOS 13_6. This is usually on opening the app after a period of inactivity. The code now automatically reloads the app which allows access to IndexedDB again.

I have updated to iOS 14 beta 5 to see if I can reproduce the error on there but I now seem to get the "UnknownError: An internal error was encountered in the Indexed Database server" error again. Only encountered this after updating my web app using skipWaiting in the Service Worker. After the page reloaded, I could no longer access IndexedDB and eventually got the error message above. I have attached the com.apple.WebKit.Networking crash log.

Still trying to create a small repro. Once I can reproduce something I will post a link.
