Hi I created a URI redirect for a page I do not want accessed. However this doesn’t seem to work.
May I ask how did you created an URL? redirect for some particular URL? 
Did you used Page Rules at Cloudflare dashboard or somehow else? If yes, may I ask if you have got any other rules configured, thereefrom might be the order & priority sequence or something else.
The redirect doesn’t work at all?
Have you tried testing in a different Web browser?
