[CLIENT] Accepting a match sometimes doesn't register

Sometimes after waiting in a queue, the ring timer appears with the accept or decline buttons but if I click Accept, the ring timer exhausts, it waits afterwards at the exhausted position, then after a moment it returns me to team building screen with a message that I declined the queue.

I also a few times got a message that I failed to ban someone despite me never making it to the champ select screen. I'm plugged in wired so it's not like it's a wifi packet loss issue.
