Moved Piwik on my webspace, now no JS and CSS showing in admin

I used to have Piwik at http://app.example.com/piwik and now it is located at https://example.com/apps/piwik. I have updated the trusted hostname in the configuration.

Now I can still log in, but the CSS and JS are not loaded. When I take a look at the URLs in the HTML source code, I can load them just fine manually. How can this be fixed?

Turns out it is uBlock Origin with many anti-tracking lists which blocks it. Disabling that on my domain fixed it.
