Can't log in to watch games

Trying to get that "watch 3 games for 300 Blue Essence" reward, and every time I try to log in to watch the game, it immediately logs me right back out. It doesn't say my password is incorrect, or username, it looks like it's logging me in properly then immediately I get the "You have successfully logged out" and I'm right back to the screen where the game is going on, and it's asking me to log in to earn rewards.
