@PishounetteI have been having these issues since season 1. These errors tend to increase when there is new event or season start. I would say there is something going on with servers in general when player number reaches certain treshold. Servers starting to fail. When season goes on and there is no so much players these errors occur way more less.
I have also noticed that when I play with friends who are on same region/servers code.net error happens way more often.
I have good and stable internet connection and other games works just fine. No need to shut down other programs or flush DNS or anything like that.
I hope Respawn is trying to find solution for these errors.
