I can't connect to the server/launch the game

[Amenti-21549]

Last night i wanted to play after 1 month of break HotS, it started updates and it remain at 0% even after 1 hour. I uninstalled both Battlenet app and Hots, download and install again; now it haves the updates but when I launch the game, it doen’t connect to the server (and I tried both “Americas” and “Europe”)
Can anyone help me with some advice, or it’s the servers?

Same problem, it is telling me something is curropted, and then the repair is stopping at 80%. Tried to uninstall and its saying battlenet not connecting. So its either just a battlenet app problem or they just totally shut the game down

These are two separate issues.

@Amenti.

Your issue is likely with the Blizzard Desktop Application itself and something interfering with its attempts to update your client.

Try doing an extended power cycle on your system. Turn off all devices including the modem. Wait 30 minutes, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.

You can try switching your DNS settings to use a free public DNS servers instead of your ISPs Servers:

We do not have individual steps for specific modems or routers so if you need assistance accessing or updating the devices, contact the device maker/provider.

Let’s manually clear the Battlenet Desktop Application and all supporting data from the system. This will not remove existing game clients.

1. Open file explorer/file manager (Right Click Windows Start)
2. Navigate to the folder where the desktop application would normally be installed. Delete that folder if it exists (usually program files x86)
3. Type the following into the address bar (not the search bar): %APPDATA% and press enter.
4. Delete the Bnet and blizzard folders inside the appdata folder if they exist.
5. Repeat steps 3 and 4 with %PROGRAMDATA% %LOCALAPPDATA% and %TEMP%
6. Empty the recycle bin.
7. Now reinstall the app to the C: Drive.

Try running your system in selective startup mode: https://battle.net/support/article/200483

Create a new administrator account: Blizzard Support - Creating a New Administrator Account

Once the account is created, shut down the computer, wait 60 seconds, restart, log into the new profile and try the app/client.

If that doesn’t solve the issue, then I recommend submitting a ticket with an msinfo attached for further investigation. (instructions for collecting that msinfo report will be on the form.)

Your issue is is likely specific to the client itself and is most probably caused by bad cloud sync data, typically with Onedrive.

Onedrive can interfere with and corrupt the settings data for Heroes of the Storm. This can happen if Onedrive is set to manage the folder where the settings variables reside in your Documents folder for Windows.

1. Open Onedrive (re-enable if you disabled it)
2. Go into settings and deselect the Heroes of the Storm Folder under documents so that Onedrive does not try to manage them.
3. Exit/close/disable Onedrive
4. Open the documents folder for your user in File Explorer(Right click Windows start, choose File Explorer)
5. Delete the Variables.txt under Heroes of the Storm)
6. Empty the recycle bin and retest the game.
