WOW51900319 Error persists even with a good internet connection. Many people have noticed that this problem has become much more prevalent after the introduction of WOW Legion.

According to multiple users, this problem is caused by Blizzard strengthening their network latency requirements. Wow Servers disconnect when Blizzard tightens their network latency. It’s what’s causing the error notice to appear in the first place.

This error warning appears even if your graphics have been boosted throughout each frame. The internet connection lags behind with a high frame rate. As a result of not being able to keep up with the servers, it disconnects.

Deciphering WOW51900319: What Does It Mean?

Before delving into the intricacies of this error code, let’s decode what WOW51900319 signifies. In World of Warcraft, WOW51900319 is an error code that primarily indicates a disconnection or loss of connection between the player’s client and the game servers.

Common Causes of WOW51900319

Understanding the root causes of WOW51900319 is crucial to effectively troubleshoot and resolve the issue. While the exact cause can vary from player to player, several common factors can trigger this error:

  1. Network Issues: Network instability, such as a weak Wi-Fi signal, intermittent connection, or high latency, is a leading cause of WOW51900319. Fluctuations in your internet connection can result in disconnections from the game servers.
  2. Server-Side Problems: At times, the issue may not be on your end but rather a problem with the World of Warcraft servers. Server-side issues, such as maintenance, overloads, or technical glitches, can lead to players getting disconnected.
  3. Add-Ons and Mods: Third-party add-ons and modifications are popular among WoW players. However, incompatible or outdated add-ons can conflict with the game, causing disconnections.

  6. Account Issues: In some cases, account-related issues, such as payment problems or account restrictions, can cause disconnections.

So, now that you’ve learned enough about the WOW51900319Error mistake and why it happens, let’s talk about how to solve it.

Method 1: Set The Background Frame Rate To 30 Frames Per Second

It’s a popular patch that solves the problem in only a few steps. When WoW switches the background, it is one of the many reasons why this error message appears. Setting the backdrop frame rate to 30 is a great way to fix the WOW51900319 problem. To learn how to do something, follow these steps.

Step 2: Select Advanced from the drop-down menu. It will force you to use advanced features.

Step 3: Next, you’ll be given the choice to adjust the maximum background frame rate. Select this option and check the box next to it.

Step 4: After you’ve activated the slider, use it to set the Max Background FPS to 30 frames per second.

WOW51900319 Error in World of Warcraft may be fixed with these simple procedures. You can now continue playing without fear of receiving an error notice.

Method 2: Reduce The FPS In The Foreground

The WOW51900319 error message appears as a result of the high graphics on each individual frame. The internet connection is unable to keep up with the high graphics and disconnects as a result. As a result, lowering the foreground FPS will eliminate this problem.

Learn how to lower your foreground frame rate by following these simple methods.

Step 1: To begin, hit Esc or click on the Menu button on the keyboard. It will open the game menu, and you must then select the System tab.

Step 2: Next, select Advanced from the drop-down menu.

Step 3: After that, you’ll see the option to set Max Foreground fps, which you may do by checking the box next to it.

Step 4: Once the slider is enabled, reduce the Max Foreground FPS setting from its current value.

Method 3: Network Troubleshooting

The problem notice appears frequently when WoW is played on a tethered 4G LTE connection. As a result, we may fix the network, and the WOW51900319 problem will be resolved immediately.

Step 1: To begin, hit Esc or click on the Menu button on the keyboard. It will open the game menu, and you must then select the System tab.

Step 2: Now select Network Options.

Step 3: To finish the operation, uncheck the Optimize Network for Speed box.

As a result of this change, the game now employs its own network protocols. The game’s network latency and ping times no longer match, which resolves the problem.

Method 4: Using an Ethernet Cable

Blizzard tightens up their network latency restrictions, which is one of the reasons for the WOW51900319 problem. As a result, anytime WoW Servers see that their network is not functioning, they promptly disconnect. As a result, we will be able to use high-speed Ethernet connections.

Wifi is not as reliable as an Ethernet connection since it fluctuates, even if it is of the finest possible quality. Optical cables are used to connect the Ethernet connections. As a result, the fluctuation is reduced when the ISP is correct.

To summarise, Ethernet cables provide a very low network latency and a high speed. There will be fewer disconnections as a result. Non-responsive conduct will be extinct as well. The WOW51900319 Error will be resolved.

Method 5: Logging Out Of 

Your account may be the only one affected by server latency. It occurs as a result of a software or technological issue. Ping times can be kept to a minimum.

If you log out and back in to your account within these periods, the problem will be resolved. It’s a simple and effective technique to remedy the problem, and you should give it a shot.

Method 6: Use A VPN 

We occasionally notice that a server in a certain location is overburdened. The server becomes overloaded as a result of a large number of pings, and the WOW51900319 error message appears. The server is no longer able to process pings.

In these cases, you can utilise a VPN from another country. This function allows you to virtually shift your location and connect to a new server. For many people, this strategy has fixed the problem. Zenmate VPN is a free VPN service that you may use.

Method 7:’s Suggested Technical Improvements has its own set of rules and regulations. These steps will assist you in swiftly correcting the problem.
