Can´t Connect to any multiplayer game

Hi, I tried to install EA APP to play the games I installed on it (BF 1, BF 4, Titanfall 2, Battlefront 2, to name a few). Playing singleplayer works just fine, but any kind of multiplayer just sends me a "cant connect" alert on each one. What can I do? I´ve never experienced this on Origin, and it´s my first time using the EA APP.

Thank you, and have a nice one.
