So, I recently purchased this game and this DLC. After playing the tutorial and messing around in the custom battle for a bit, I decided to try to play multiplayer. I open the multiplayer tab, and create a character. Then ,I click on "Join a Game" and after a second it gives me the message "Error: Unable to connect to server." I know for a fact that my internet is working correctly. I tried hosting a game out of curiosity, and it successfully launched. So, I'm asking for some help. What can I do to fix this?
