So I had the term "nus" entered in my routers parental controls and it was working fine until yesterday. I was already on 5.5.0 but wanted to make sure it didn't update any further & until last night I had the red X at the bottom of the screen & any update check would fail. The red x is now gone and an update check completes without error. I checked the router settings and everything is good on that end & also checked several sites with "nus" in their url and it is indeed still blocking any url with the term. So... why is it no longer working in the Wii U end? I went many weeks with the red x, but now it's just not blocking it any longer - but only on the Wii U. Confused.
