I forgot to add - 404 errors in browsers generally come when a URL has been mistyped or does not exist on a server.
I added a path to the end of the reddit URL below to show you. The web server for reddit has received the request, but doesn't have a subfolder called "battery" to show - hence it returns a 404 response
404 Example - https://www.reddit.com/battery
curl -I https://www.reddit.com/battery
HTTP/2 404
Double check you have the correct URL in your apps and there are no typos
