Windows

  1. Closing background applications can resolve conflicts between Blizzard games and programs running in the background on your computer.
  2. Security programs can interfere with the game's connection to our servers, especially after a patch. Disable or temporarily uninstall your security software.
  3. Issues with network devices may cause connection instability. Power cycle network devices to restabilize a connection.
  4. The Domain Name Service (DNS) cache saves connection data. A bad DNS cache entry can cause connections to fail. Flush your DNS.

Note: A malware program called Scorpion Saver may cause this error. It's difficult to remove and may not be caught by normal antivirus scans. To identify an infection, gather your MSInfo and check Software Environment -> Loaded Modules for "Adpeak." If it appears on the list, we recommend you contact a certified computer technician in your area for assistance removing the program.
