Playing a must win game in champs to get 8 wins. Whole game was glitching

I tried to play squad battles yesterday & today but I keep losing connection & have to reconnect to eat servers again & again. Not only that when I'm doing an SBC as well, it suddenly lags & it says that I lost online connection. I checked my router & it works fine. Its ur servers which has a problem so fix it because its becoming a headache & it's annoying as hell right now
