Can’t connect my apps to my tv!!!!

Just resonantly today I wasn’t able to connect my YouTube or my Netflix to my tv. I don’t know if it’s the new updated version of the IOS (IOS 11) but only 2 weeks ago it was working perfectly fine. If someone can contact me or have any suggestions on how to fix it let me know immediately.
