Hi ipadmannl!
Firstly, welcome to the forums
Secondly, I'm sorry to see that you are experiencing issues joining matches.
Where are you connecting to the game from, and who is your internet provider?
Do you own a physical copy, or a digital copy of the game?
Can you go through the steps found here, esp[ecially the part about port forwarding. Doing this will ensure that your connection is set up correctly for the game.
If you are still having trouble connecting after this, please let us know.
