Game shut down by itself during Queue for Storm League

Hi,

I queued for Storm League and got into a match.

But before the draft screen appeared, the game suddenly shut down by itself.

I immediately opened the game and suddenly lost around -400 points. No penalty was given and I could not find the game in my match history.

Can someone in Blizz look into this? This has never happened before and I do have a strong PC.

I would be happy if I could get back my 400 points…

Best regards Albe
