Can you send us sample request ids and timestamps for those 404s?

Our logs indicate that the 404s were returned by the user application (i.e. your server) and it was that status code that our service forwarded to your client. Also, for the HTTP responses in the provided HAR file, the value for the X-Powered-By header is Express which would also come from your server, not the Dev Tunnels infrastructure/service.

It may that your client-side browser cache is requesting files that have since been removed/renamed on your server. For example, in the HAR file, there's a GET request to http://s5198zdw-5000.euw.devtunnels.ms/chunk-EC5ID3OO.js that contains the caching headers if-modified-since: Wed, 31 Jul 2024 05:29:46 GMT and if-none-match. The 404 response was sent at Wed, 31 Jul 2024 05:41:44 GMT. If you're using something like webpack, it may be producing files with different file names during development as your code or imports get updated.

A solution here may be to disable browser caching, e.g. via Browser DevTools.
