Google Analytics: View filter not picking up any traffic


I have created a new view (a copy of the main one) and set a filter as follows:

enter image description here

However, if I visit any URL with that inside of it, nothing gets picked up on the real-time view. However it does get picked up on the main view, where there are no filters.

I can’t click on the verify link as it’s saying the service isn’t available

Any ideas?
