Complete failure to join games although literally everything works

So, in another great turn of events because of this AMAZING client, I now have a random issue that will cause league to lie that the game cannot connect to the server while I am actively online.

Anyone got any solutions? I solved it the first time by just randomly signing on and off and running in admin but I dont remember what actually did anything because the solution to this is literally random.

Do not answer with "check firewall/antivirus" because I've already done that and am fully aware that League is set to run without any restrictions on both. This is solely a league client problem and if I get a leaverbuster the next time this problem appears and refuses to let me join the game, supports gonna get their ass torn up.

I dont understand why this client has so many random ass issues that appear out of nowhere but i'm over it.

Thanks for reading, this is just super fucking stressful and im over letting my friends down because of this dumbass client.
