Charts not working since 3.0.2/Docker

Hi!

Since I updated my OpenHAB Docker to 3.0.2 the charts are not showing up.

In the UI I can see a miniature chart like this:

But When I click on analyze:

All is empty.

I cannot see any error in logs inside the docker container.

I see 6.app.css missing in the browser console, and there is an SSE error: Event source connection broken.

Any idea what could be wrong?

By chance, it happens that I got I new Laptop, installed also Ubuntu here and also using Firefox.

But now, the charts work.

I cannot figure out what was causing the charts not to work but seems to be browser related.
