Frustrating high ms, i can't play league anymore !

Hello, dear riot supports and community,

I have been playing league as always with no problem, I have a connection of 200mbs my ping always around 30-50ms, yesterday been playing my games as usual 45ms, finished the game, next game, I was in the lobby with friends, and then game got frozen at the "accept match" box, of course, I pressed the accept button, and everything stayed frozen for so long, and got disconnect box says 'exit the game', I restarted the client , I was like ok this is just another bug/glitch as always happens, but since then whenever I play a game or do a custom game my ping is 160ms for no reason at all, tried so many solutions and fix, and nothing at all, it seems I can't play the game anymore, and I don't know what to do about it, my connection is really great 200mbs, can even stream while playing league, add some family devices connected and I'm really just fine, but now since yesterday that shit happened, the ping is 160ms and still right now and its really frustrating.
