Symptoms

  • Hearthstone disconnects during a match.
  • The game cannot sign in or reconnect.

Likely causes

  • Service or region issue. An outage or a different selected region can affect sign-in and which account data appears.
  • Local connectivity. Wi-Fi interference or a connection change can interrupt a session.

Check service and connection

  1. Check Battle.net’s current maintenance or service notices.

  2. In the Battle.net launcher, confirm the selected Hearthstone region and account.

  3. Blizzard’s support forum identifies Americas, Europe and Asia as region choices. Availability can change.

  4. Check another website. Compare Wi-Fi with Ethernet where possible.

  5. Follow Test for packet loss on a Mac with ping to compare the router and internet connection.

How to fix it

  1. Wait for announced maintenance to finish, then reconnect.

  2. If the problem occurs only on Wi-Fi, check signal and interference. See Weak Wi-Fi signal on a Mac.

  3. If issues persist, follow Blizzard’s connection troubleshooting and provide the requested information.
