Help me please!! Cannot use social media apps on mobile data-WiFi works

[AC Question]

For the past two days my Samsung Galaxy s5 will allow me to connect to everything else including social median without using wifi and only using my data, but I cannot connect to Facebook with my data only if I'm on wifi. How do I fix this? I have tried deleting fb app and re downloading it, try to update my phone but I had no update. Turned my phone off and then back on again as well. So what do I do. I also have strait talk wireless plan. So is that something only they can fix?
