When you try sending a request to “http://127.0.0.1:8265/static/js/main.4e04a38d.js” directly either using something like curl or from a new browser window, does the content of that file download? Or do you also get a 403?
I’m not sure what would cause this to break in the new version of ray. This issue seems to be on the side of the dashboard process which serves the static content necessary for the ray dashboard web application. But we did not change anything there recently.
