Quick Summary
Error WOW51900319 generally indicates a disconnection issue between your computer and game servers. This could be due to problems with your internet connection, the game server, or interference from other programs.
Common Causes
- Internet Connection Problems: A weak or unstable internet connection can cause disconnections.
- Game Server Issues: The game servers might be temporarily unavailable due to maintenance or unexpected issues.
- Firewall or Security Software Interference: Firewall or security software on your macOS might be blocking the game's connection.
- Outdated Network Drivers: Outdated network drivers can sometimes cause connectivity issues. Although MacOS typically handles drivers, firmware issues on the router/modem can sometimes manifest similarly.
- Router or Modem Issues: Problems with your router or modem, such as overheating or outdated firmware, can lead to disconnections.
Step-by-Step Fixes
Method 1: Restart Your Modem and Router
Step 1: Unplug your modem and router from the power outlet.
Step 2: Wait for 60 seconds.
Step 3: Plug your modem back into the power outlet and wait for it to initialize (usually indicated by steady lights).
Step 4: Plug your router back into the power outlet and wait for it to initialize.
Method 2: Check Your Internet Connection
Step 1: Try accessing other websites or online services to ensure your internet connection is working correctly.
Step 2: Run a speed test to check your download and upload speeds. A low or unstable speed can indicate a problem with your internet service provider.
Step 3: If possible, try connecting your computer directly to the modem using an Ethernet cable to bypass the router. This will help determine if the issue is with the router or the internet connection itself.
Method 3: Temporarily Disable Firewall and Security Software
Step 1: Temporarily disable your firewall or security software.
Step 2: Launch the game and see if the issue persists.
Step 3: If the game works correctly with the firewall or security software disabled, you need to add the game executable as an exception in firewall settings.
Step 4: Re-enable your firewall and security software.
Method 4: Flush DNS Cache
Step 1: Open Terminal (Applications -> Utilities -> Terminal).
Step 2: Type sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder and press Enter.
Step 3: Enter your administrator password when prompted.
Step 4: Restart your computer.
Method 5: Use a Wired Connection
Step 1: If you're using Wi-Fi, try switching to a wired Ethernet connection.
Step 2: Connect an Ethernet cable from your computer directly to your router or modem.
Step 3: Launch the Game and check if the problem is resolved.
