Service worker in Safari

Question

I have a major problem with service workers, or what I think is a service worker related problem. The problem I have (only in Safari) both on Mac and iOS is that every second time I visit a route I got a 504 (Gateway Timeout) message in the console and no data is fetched from the server.

Thanks in advance,

Mattias

Disabling etag from server side fixed my issue.
