Chrome returns ERR_FAILED for localhost

Question

After some experiments with PWA I've encountered a strange issue with Google Chrome only. Every other browser works just fine.

When I load http://localhost the response is: "This site can’t be reached"

The error status is: "ERR_FAILED" (404)

Note:

• "ping localhost" returns 127.0.0.1 (as it should be).

• wget -qO - 'http://localhost' loads the correct content in terminal.

• every other browser loads the correct content.

• the setting in /etc/hosts leads to 127.0.0.1

• if I access the content via IP (127.0.0.1) it loads just fine.

• I have cleared the browsing cache

• the PWA cache seems to be clean.

• The offline box in the network tab is not checked.

If anyone has any ideas on what could cause the issue please share. The only clue I have is that in the sources tab of the code inspector there's the content of sw.js (my service worker) but there's nothing to do with it.

Answer 1

I came out that the issue was caused by a cookie called ServiceWorker.

After deleting it everything works fine.
