Why I can't start team league?

I got some problems with TL, I think it is some patch but haven’t seen some changes about TL… I started play team league week ago, but I can’t not play TL because it showing me requirements… I have 50 level, I’m silver 5 and now I can’t play. Please help

Maybe you disconnected and have to play some matches in QM first. Or just restart the game and/or your computer.
