How can I unblock cdn-cf.fabric.io?

Question

I don't know why but I am occasionally seeing this error after being logged for a while.

We couldn't load assets!
Please make sure cdn-cf.fabric.io is not blocked and try again.

The only way to get out this screen is by cleaning up my cache. How can I unblock this host?

More details:

• Operational System: macOS Sierra Version 10.12.6
• Chrome version: Version 61.0.3163.100 (Official Build) (64-bit)

It happens to me straight after cleaning up my browser data, login and refresh the browser.
