What Causes Error Code WOW51900118?
In most cases, this error occurs due to unscheduled or emergency maintenance. However, you may start getting this error due to a network issue on your end. Typically, you can get this error after getting stuck on the Retrieving realm list or Logging in Game screen, or while playing WoW. We have compiled a list of the most common causes for this error blow.
- Server maintenance. Blizzard can sometimes shut down its servers for maintenance. Usually, scheduled maintenance is announced on the forums or inside the game, but unscheduled and emergency maintenance is not uncommon. As a result, you won’t be able to connect to the game and get the WOW51900118 error. Check the official WoW Realm Status webpage, Blizzard’s forums, and Blizzard’s social media pages.
- Misconfigured network settings. A stable and reliable internet connection is vital for World of Warcraft to work correctly. If you have an unstable WiFi connection or your network settings have been tampered with, try switching to an Ethernet connection or reset your network settings to default settings.
- A faulty DNS server cache. Your ISP-provided DNS server cache may become corrupt and trigger the error. If that’s the case, flushing your DNS server cache will fix it.
Before trying our fixes, here are some tips:
- Use a different Internet Connection. WoW requires a stable network connection. Therefore, try switching to an Ethernet connection if you use a WiFi connection. You can also connect to the Internet via a mobile hotspot.
- Use a VPN service. If a WoW server flags your network, preventing you from connecting, try to connect using a VPN. However, if you already use a VPN but get this error, try turning it off.
- Close all network-intensive background applications. Some apps on your PC may use a lot of your network bandwidth. Closing such apps will ensure WoW has a stable and fast connection.
