Host error

IDK if its really that but heres my problem.
I log into the game fine. But when i start to load a match, it goes all the way and then puts me back into the lobby saying "Fail to Connect to Host Server".
Normally if i get something it just takes me out of the game but here im back in the lobby and i could start to load another match but i get the error again.
Out of about 12 matches ive tried i only succeded in 1.
anyone know a solution.
