Apps cannot connet to internet

[AC Question]

Well i have Galaxy S6 edge and its connected to internet.. i can excess to every website.. but some applicatons like zedge, facebook, 9gag, netflix, 2k NBA cannot connect to internet... if i used a VPN such as betternet then it works ... any idea that is it my phone problem or my wifi's error..
