Here's what's on console:

(unknown): #2514: An unknown error occurred when fetching the script.  [Service Workers]

I am get the above error on my dev console when the service-worker has taken over or skipped waiting and I reload the page with the network turned off. The thing is I get plenty of fetch errors on the console because obviously none of the requests are passing through but there is just one error on SW dev console (Click image):

What is it about?

The error message itself isn't telling much about the issue, like the request it bailed out on or similar.

I think you need to add your corresponding https certificate in your browser. for chrome go to setting -> advanced settings -> manage ssl certificates

under authorities tab click import then add your .crt file. restart browser it should work fine.
