The game keeps constantly closing when I try to open Hearthstone it still takes me like 20 tries after it finally opens i’m afraid of closing Hs cause I have to do that every day and it has been like 2 weeks and a threat that lot of people have complained about and your “solution” has not solved anything. YES I tried deleting the cache the folders and all the stuff you put in a similiar post and it didn’t work will you take this more seriously blizzard? Its really annoying that people can’t play cause stuck at loading screen for an eternity and for what to have a “Game closed”

Thanks, Cirius! Appreciate the thought Right now, we haven’t seen any successful workarounds or fixes for this error, but reporting this to our team greatly helps with the tracking for potential escalations ^.^
Same problem here. Stalls with hs:ct;netcachedecks=0:netcachecollection=0:netcachecardvalues=1 or
HS:NT304:303:0.
unable to log in after trying like 40 times.
Reinstalling the game fixed it for me
I tried reinstalling but it did not fix it for me, where did you get the error that you mention ?, I want to check if its the same error that you had
This message is shown on the top: HS:CT;NetCacheDecks=0;NetCacheCollection=0;NetCacheCardValues=1
This has been happening since the most recent update and it hasn’t fixed since. Please help.
Same problem here. We pay a lot of money fo this game, and right now I’ve been trying to get down to rank 5 for days. Missing out on the past two weeks of the season isn’t cool.
Hey folks,
Are those of you having this issue using any deck tracking software (Hearthsim, Innkeeper, Hearthstone Deck Tracker, etc?) If so, can you try temporarily uninstalling them and see if it clears up?

I have uninstalled them and relaunched the game and it still doesn’t work.
Even after uninstalling Hearthstone again, the game still won’t work.
I also sit and wait for a solution to this terrible, insoluble problem. It seems so far that HearthStone is over for me …
Try uninstalling Hearthstone, maybe even battlenet with Revo Uninstaller, select all the needed registry keys and left over files both times. Then restart and reinstall.
Be careful deleting registry keys though
Worked for me
Thanks for the report, KalLaba! I’d assume if that helped, a New Admin account and clearing the Battle.net Cache and Tools on the New Admin account may help as well.
We do not recommend to clear registry files or registry cleaners as this may cause issues with the operating system. This hasn’t been successful so far from our reports on troubleshooting. If the New admin and clearing the files helps, please do let us know! If not, please do reach out to our Technical Support team.
We are looking at these situations on a case to case notice as there’s been a few several different causes and issues so far. If we have a solid resolution that is consistent, I’ll update them here.

Errors every time logging into US or NA. I can get into Europe just fine though.
Although I just realized you’re starting over on Europe in the tutorial area with no cards? What?

I have been getting the error below for the last few days after the latest patch. After a few attempts trying log in I do usually get in but it’s inconsistent.
HS:CT;NetCacheDecks=0;NetCacheCollection=0;NetCacheCardValues=1
I tried the steps in this post but it doesn’t resolve the issue: Trying to reconnect to a game - #4 by Caterpepi
I then tried to log a support ticket, but the Contact Support page is stuck at “One moment, please. The page is loading.”
@kira, I moved you to this thread. The reconnecting issue is different from the Netcache errors. Please try the recommended steps on this post. If you continue to experience issues with contacting our Technical Support team, have you tried a different browser or tried an alternative connection?

@ deFox, Please try the recommendations on this post. If it persists, please contact our Technical Support team.
