High Latency issue on Dreadmaul server

Here’s the issue that I would like to highlight:

I’ve been receiving high ping issues which resulted in lag and delayed casting of abilities after I pressed the keys of them on my keyboard. I’ve checked my modem and internet connection and it is fine. The latency only starts going up when I start queuing for Rated Solo Shuffles and goes up even higher when I’m in a Rated Solo Shuffles game. This has never happened to me before despite me playing on Dreadmaul for the past few days, weeks and even months. Even when I was playing on Frostmourne, there wasn’t any issue. Just want to kindly highlight this problem to the GMs so that this problem can be tackled earlier hopefully. Thank you.
