I have been getting this error code and I see that the problem has been going on for almost a year now. I don't know what the problem is but there has to be some way to solve it.
It is currently April 2019 and this issue is STILL GOING ON! I understand that changing my ping site works, but why do I have to connect to a different server? This causes lag and also language barriers don't help gameplay. I don't understand why I can't connect to my 11ms Virginia server but instead, I have to connect to the 103ms Germany server just to play the game. There is nothing online that I can find that fixes this yet and I'm beyond upset at this point. This also ONLY occurs in hero showdown. Every other game mode that I have played works while I'm connected to the Virginia server, but not the game mode that I'd like to play.
