High ping only in league of legends?

Whenever I go in a game of LoL my ping is a constant from 290 to 350, it doesn't go below that. This has started happening yesterday, but only for a couple of games. Today it's been going on for a while. My discord ping is 40. When I went in Rust(game) my ping was 30. I went in practice tool right after that and boom, 300 ping. Only in League. What's going on? {{item:3070}} {{item:3070}} {{item:3070}}
