Browser loading forever on CentOS7


I noticed that on my CentOS 7.0 Foreman instances, my browser loads all
pages "forever". It's waiting for some resource to be loaded and I am
not able to tell which one is that.

Anyone experience the same? Or has a tip how to find out? The Chrome
developer tool does not show me resources being loaded, I only see those
which were already loaded.

Everything is fine on CentOS 6.6. I experience this for several weeks
now with nightly.
