Not an Outright Block

I’m having trouble getting to a website I use that is associated with a mobile game. Ilmina.com provides analysis and insight for the Gung Ho mobile game, Puzzle and Dragons. When I look at the category CleanBrowsing assigns to the site, its rated PG and given an entertainment category. I can browse to the site. However, when I go there, all I see is that an error occurred and it failed to load data. When I switch my router DNS over to my ISP (instead of CleanBrowsing), the site works properly. Could someone look into the domain and the data the site uses to see if a block is occuring? Thanks.
