Banning champions and locking in my champions error

I have been banning champs and right when I click on ban it freezes and it either says error happened and bans it a sec after or kicks me. After I get out of ban phase the champ select phase also does the same but this time it kicks me out as in I never selected a champion and it tells me error could not select your champion. I have lost LP twice because of this in a row now, any thoughts on what is causing the errors?
