What Is The World Of Warcraft Game?

World of Warcraft (WoW), developed by Blizzard Entertainment, was globally launched on November 23rd, 2004. It is an MMORPG game and has been addictive to fans since its release.world of warcraft

It is set in the high-fantasy Warcraft universe and allows players to create their characters, explore the world, complete quests, and interact with other players online. In WoW, players can choose to be a member of the Horde or Alliance faction and choose from various races and classes, each with unique abilities and skills.

The game is set in an immersive and vast world filled with various environments, creatures, and characters and features a rich and complex story that players can explore at their own pace.

Occurrence And Possible Reasons For The Error

Blizzard Support states that the most common meaning of Error Code WOW51900319 is “You have been disconnected from the server (WOW51900319)” This error occurs when your game cannot communicate with WoW Servers anymore.

Blizzard states that one can get other errors like “Disconnected from World of Warcraft” or “Disconnected with error BLZ51900075,” which technically means the same as Error Code WOW51900319.

But users have reported getting this error even with correctly running internet connections. This error has increased manifold after the release of WoW Legion. According to Blizzard Support, this error was very discrete before the release of Legion.

Some users speculate that this error can be caused due to Blizzard tightening up their network latency requirements. Hence, WoW Servers immediately disconnect when the network does not respond.

Another reason that users pointed out is the increased graphics over each frame. Therefore, when one plays WoW at high fps, the internet connection cannot keep up with Servers due to network latency and hence disconnects.

Also, no correlation between the software, PC Configuration, and ISP causes this issue. Some users also report getting this error only when they play as Demon Hunter in Dalaran. So, maybe you should stop doing that? Haha! Anyway, jokes apart, let us now talk about the Fixes.

Problems Due To WOW51900319 Error

The WOW51900319 error can cause various problems with the World of Warcraft game client, including the game crashing or freezing or the error message appearing when you try to launch the game. It might prevent you from accessing the game and can be frustrating.

Sometimes, the error may be caused by a problem with your internet connection, leading to “I keep getting disconnected from WOW.” So it’s important to check that your connection is stable and there are no issues with your network.unstable internet

The error could be caused by other programs or applications running on your computer and using many resources, so it’s a good idea to close these programs before trying to run the game.

If the problem persists even after trying these steps, you may need to repair the game client or delete the game cache files, as described in my previous response. Don’t hesitate to contact Blizzard Support for further assistance if you need help with these solutions.

How To Fix The WOW51900319 Error Code?

This is another fix that solves the WOW51900319 Error in World of Warcraft. As we mentioned earlier in the reasons for this error, increased graphics over each frame sometimes causes this.

Hence, when one plays WoW at high fps, the internet connection cannot keep up with Servers due to network latency and thus disconnects. This shows disconnected from server WOW51900319 error.

Network Fix

Another fix for the WOW51900319 Error due to network latency issues is the Network Fix which is popular in Reddit threads and has helped many gamers. It states that this issue is more likely to occur if the game is played over a tethered 4G LTE Connection.


  1. First, press Esc or click the Menu icon in the game to open Game Menu and click to go into System Tab.settings menu wow
  2. Now click to go into Network Options. Afterward, click to uncheck Optimize Network for Speed.network optimize wow

This results in having a longer delay between such disconnections as the game stops optimizing every time according to the network, and this causes the game to stick to its network protocols and ping times instead of changing them according to the network.

This causes the network latency and ping times of the game not to line up and thus helps solve the issue.

Using An Ethernet Cable

As we mentioned earlier in the causes, this error can be caused due to Blizzard tightening up their network latency requirements. Hence, WoW Servers immediately disconnect when the network does not respond.

As with internet connections, high-speed Ethernet connections are best for gaming and mostly outperform Wi-Fi or LTE Connections of the same bandwidth and speed.ethernet cable wow


This is because the latter two fluctuate even if they are of the highest stature. Ethernet connections run within fiber optic cables and are less likely to fluctuate if your ISP is good.

Thus, Ethernet cables have less network latency and high speed, which cause fewer disconnections and non-responsiveness with the World of Warcraft Servers and thus fixes the WOW51900319 Error.

Logging Out Of Battle.net

Sometimes, even though widespread, this issue can be due to a Server lag in response to specifically your account because of software or technical problems. The ping times may be lowered, or the Server may become unresponsive to your account, anything specifically.log out battle net

At such times, a simple Logout and Re-Login into your Battle.net account in World of Warcraft can solve the Error WOW51900319. Such a case happened with a fellow Redditor who let the world know about it. Maybe, that will help you too?

Use VPN Of Some Other Region

Sometimes, a specific region’s WoW Server might be overload due to many pings, especially during peak times. This may cause the game to give an Error Code WOW51900319 because the WoW Server cannot serve any more requests.vpn wow

Using a VPN of some other region fundamentally changes your location, and thus your Server is different from the previous one. This has solved the WOW51900319 error for some people.
