Thank you, folks and appreciate the connection tests! We are seeing connection issues with Scandinavia and Blizzard Services that may impact a few of you here. I’ll try and see if we can push this up the ladder and update you all here, but we only have 4 unique WinMTR tests provided. Our network engineers may need more to look into this issue further.
If you are experiencing either one of these errors:
Encountered some network issues while reading your card collection.
Closed - We just ran into a network problem as we were loading up all the cards in your collection. Please relaunch Hearthstone to access your collection and resume your duels!
This is not the same issue as the reports here. Please refer to this forum post, so that we can make sure we are tracking each situation accordingly.
