Over the course of the last few seasons, I have had to use Cloudflare One Client with Traffic and DNS (HTTPS) mode, because without that my game would just be stuck on entering game for 10+ minutes. Or even if I can get inside the game, and play some matches I would just get disconnected. I don't know why this has been happening when I could normally play the game without Cloudflare like a year ago. I usually don't post in this subreddit, so I am not accustomed to the rules. Hence I apologize if this isn't the problem place for this discussion.
