HTC M7 blocked facebook

Hello!
I have a weir problem with 2 htc m7
The 2 of them behave in the same way, they don't open facebook, is like if the ip of the server was bloqued, i tried accesing facebook from the browser, facebook app and mesenger.
Im frustrated and I don't know what to do.
They have S-off so they can be routed but the are not routed, so any suggestions :S ?

Let's block ads! (Why?)
