Chrome Https request canceled and gets retried on http

Question

From Chrome 93 we start to see the follow behavior.

1. Browse to a specific page
2. Only when you click in the navigation panel on the URL and press enter (for example the reload button works fine)
3. the page reloads and after a few seconds the requests get cancelled
4. A new request starts but instead of https its now with http.

At first, we thought it is in the webserver, but the server log does not show any request, most likely because a cancellation is a client-side Chrome action.

• Its works fine in other browsers.
• There are no service workers installed
• We tested it on multiple machines in private mode, to avoid any interruption of 3th party plugins
• Whe the request including cookies and sessions is copied to postman, the request loads normal.

Answer 1

During a navigation request: After waiting 3 seconds on https, a new attempt is started on http.
