Ways to cope with the Error Code DUHOK – LESTER

Mentioned next are some of the ways which you can practice in order to resolve the error code DUHOK – LESTER on your Call Of Duty: Vanguard.

By Inspecting the COD Vanguard Server Status

Being able to access a game\’s server status is a crucial element of any gamer\’s game experience. It can impact whether or not you\’re able to play your favorite game or not.

You should be checking the Call of Duty: Vanguard server status frequently so that you will be able to identify any problems and adjustments that need to make in order to ensure that the gaming experience continues in an uninterrupted manner.

Whether you\’re prepping for a major match or just shooting some hoops with your friends, you can usually find gamers logging on to Call of Duty: Vanguard for some multiplayer action.

If the servers are down or experience any other problems, we recommend that you check the official server status page on the developer\’s site. However, right now, there are no reported server issues.

By Examining Your Internet Connection

It’s also worth mentioning that you should check the settings of your wireless internet to make sure everything is running smoothly. Because it is very easy most of the time that poor or unstable internet service can lead to multiple server issues.

In some cases, your internet provider can be majorly responsible for the problems you are facing. Moreover, it is important to check if there isn\’t a problem with your internet connection.

Besides, poor download speeds can often be the culprit — whether it\’s due to a poor local network or a weak wireless connection. In most cases, switching to a wired connection or another network protocol will help you solve connectivity issues.

Connecting to servers and downloading secondary resources is crucial for a trouble-free gaming experience. If you are running into problems, try connecting to a different server or switching the download speed settings on the client.

By Restarting Your Wi-Fi Router

One quick way to check if the internet is working again is to power cycle your router. First, turn off the router and unplug the power. Let it sit for a minute or two, then plug the power back in and turn on the router again. Try connecting to your Wi-Fi network and see if the internet issue still persists. Power cycling the Wi-Fi router might fix the problem if it was just a temporary blip in the connection.

By Eschewing the New Update of COD Vanguard (PS5)

As the first version of Call of Duty: Vanguard was just recently released on the PS5, it is recommended that you avoid preloading the update until the developer fixes a few glitches. This will help you save your time by not downloading versions that are currently unavailable for use.

Also, once you have logged into your PS5, make sure to avoid logging into Call of Duty: Vanguard for the next few weeks. The latest patch i.e., version 1.008 may cause widespread connection errors or development issues — neither of which is good for anyone!

Until the developers release a fix, you should avoid logging into Call of Duty: Vanguard. If you\’re looking forward to playing through the new content, wait until a game patch has been released.

By Deactivating On-Demand Texture Streaming

The biggest game-changer in the world of texture synthesis is a relatively new technology called On-Demand Texture Streaming. It is a great feature that can improve graphical fidelity. However, it requires an internet connection that\’s stable enough to handle the extra data load in the midst of a game.

If you\’re experiencing lag or stuttering, try reducing the texture quality to stabilize your performance. On-demand network streaming is an excellent option for gameplay, but it can cause additional network stress.

So it is recommended to disable or deactivate it, in order to avoid unnecessary circumstances during your gaming time. For disabling it, follow the steps mentioned below.

In-Game Menu -> Navigate to Settings -> Disable or Turn Off the On-Demand Texture Streaming option under the Graphics Tab

By Restoring or Repairing Game Files

Over time, your game files can get corrupted due to a number of reasons. The process to fix them is, however, simple, all you need is the app. It can check for any missing or broken game files on your gaming rig and help you resolve them quickly.

If a game file is distorted, the client can be your best companion to repair it. This not only means that players will be able to play without any issues, but they will also gain up to 20% more speed while playing.

The method of restoring or repairing game files with the app is mentioned next in bullet points.

  • First, open the desktop application.
  • Next, from the library, track down the COD Vanguard game.
  • Now, pick Options, and then tap on Scan and Repair.
  • After that, you need to wait for some time until the repairing process is successfully complete.
  • Finally, relaunch the game to test whether the issue is resolved or not.

By Power Cycling Your Console

Sometimes the Wi-Fi connection and router are not the problems — your gaming console may have some issues with connectivity. Try a power cycle to your console by unplugging it, waiting for 30-60 seconds, and plugging it back in. This may solve any connectivity issues you are having with your console.

Afterward, check with your gaming system and see if there are any outstanding updates or firmware to download. However, this is one of the biggest worries that console owners face.

Power Cycling Your PlayStation

  • First, press and hold the power button on your PlayStation console until you hear two beep sounds.
  • After that, what you need to do is unplug the console power cord.
  • Now, wait for around 10 seconds. (or in some cases for 10-30 seconds)
  • Next, plug in the console power cord again.
  • Finally, relaunch the PlayStation console to ensure whether the problem is resolved or still persists.

Power Cycling Your Xbox

  • Start with pressing and holding the Xbox Power Button for approximately 10 seconds.
  • This will power off your Xbox console entirely. Now, move on and pull out the power cable from the socket.
  • After that, you need to wait for around 30 seconds.
  • Next, plug in the power cable back.
  • Finally, relaunch the Xbox console to examine if the issue is fixed or not.

By Linking Your Activision Account to the Device

You may run into problems during log-in or connecting to the game server when you link your COD game profile to your Activision account. Make sure that your game profile is properly linked up to ensure smooth log-in and connection.

It seems that some players are experiencing difficulties when trying to link their game profile to an Activision account. To ensure optimal connectivity, it is recommended you link up your game profile to the Activision account and sync your progress. The information on this site is published in good faith and for general information purposes only.

By Changing Maximum Transmission Unit (MTU) Settings on PS4/PS5

If you\’re experiencing the COD Vanguard Connection Failed Update Required Error, revert back to your MTU settings. Make sure you have the correct MTU for your PS4/PS5 console and Computer — if anything changes, the servers won\’t be able to connect with your console or PC appropriately.

Having too high or too low of an MTU for your network can pose problems for connecting to a game server. This will definitely cause issues that will make it impossible to connect to multiplayer servers. We are again saying that if you’re still facing connection issues, please double-check your MTU settings.

By Factory Resetting Your Router

Resetting the router is the first step in troubleshooting internet issues if your internet goes down temporarily. When you reset the router, you clear out temporary data that may be causing connectivity problems, and restarting the router re-activates its connection to the internet.

If you\’re having trouble connecting to your Wi-Fi network, the first thing you need to do is check if you have the latest firmware running on your router. Sometimes glitches or short-term data issues with your router can lead to problems like slow internet speed or dropped connections. The quickest way to resolve these issues is by resetting your router.

If you have a wifi password, change it to make sure your frustration problems are gone for good. You can do a factory reset on your wireless router to check if that fixes the problem.

All you need to do is press and hold the Reset button on your router for around 10-15 seconds until all the LED indicators stop blinking and start blinking normally again. After approximately 30 seconds, try to connect to the Wi-Fi network again. This method will surely assist you in solving your problem in most cases.
