Running in browser gives a black screen, no errors

Godot Version

Question

I’ve put together a super simple pachinko drop thing and everything runs perfectly running with F5, but when I Run in Browser or export and run an HTTP server myself I just get a black screen with no errors in the dev console in firefox and the below errors in edge that I can’t figure out how to resolve. Any ideas?

The ‘viewport’ meta element ‘content’ attribute value should not contain ‘user-scalable’.

‘content-type’ header charset value should be ‘utf-8’.
