Constantly Losing Connection to game servers

Whether it is Call of Duty Modern Warfare, or Overwatch, I have nonstop been getting dropped from games randomly due to me losing connection to game servers. I’ve tried uninstalling and reinstalling, and even installing games to another drive but I have had no luck. I’ve been fed up since this morning due to me getting a Leaver Penalty on something I could’nt control. And my wifi is not the issue, as games in other launchers run perfectly fine, but other than that this is the only issue I have had with the Launcher. If ANYONE can help it would be greatly appreciated. Thank you.
