Unable to Login + Lag in-game

Playing a ranked game, usually my ping is 30-35 ms, but I notice some lag when I'm inputting right click commands so I check and I see I have around 50 ms. 10 minutes later it goes back to normal, but then a few minutes later it suddenly spiked back up to 50, but it was different this time as it would constantly change (which if you've ever dealt with, is actually worse than a consistent high ping). Then I spike so hard I actually can't even move, proceed to get chain CC'd, and die. I figure reconnecting to the game will fix the issue, but as soon as I try I find out I can't reconnect to my game.

So I restart the client and now I can't log in (screenshot attached)
