How to Fix Call of Duty: Vanguard ‘Server Snapshot’ Error?

A big portion of the Call of Duty: Vanguard player base are reporting that they’re regularly being kicked out of online matches and they end up seeing the ‘Server snapshot error‘ message. This problem is only reported to occur for PC, PlayStation, and Xbox players.

Call of duty Vanguard Server Snapshot Error

We’ve looked into the issue thoroughly and analyzed dozens of user reports and we realized that this problem actually has multiple probable causes. Here’s a list of potential culprits that might have something to do with the error that you’re experiencing when playing Call of Duty: Vanguard:

  • Domination game mode glitch – As it turns out, the vast majority of users that are experiencing this error after being disconnected from an online game happen when they play Domination maps. Until the developers manage to pinpoint the issue, you should be able to play the game without experiencing this issue.
  • NAT is not Open – You should expect to encounter a lot of instability issues in case your NAT Type is not Open. To fix this issue, you will need to do some changes to your router settings (and/or PC).

Now that you are aware of every potential cause that might trigger the Snapshot error with Call of Duty: Vanguard, let’s go over a series of fixes and workarounds that might allow you to fix or avoid this problem when playing the game on PC.

Stay Away from Domination game mode (for now)

The vast majority of player reports involving the Vanguard Server Snapshot Error occur when playing Domination mode. The devs have yet to acknowledge a direct connection, it’s clear that the sheer amount of user reports will prompt them to investigate and fix the issue.

While the developers over at Sledgehammer Games manage to identify and fix the problem, our advice would be to stay away from playing any type of Domination mode (regardless of the map).

We’ve made a list of game modes that don’t seem to have this problem. Consider playing this mode until the next game patch gets released:

  • Free-for-All
  • Team Deathmatch
  • Search & Destroy
  • Kill Confirmed
  • Hardpoint
  • Patrol
  • Control

If you’re experiencing this error when playing other game modes, try the fix below.

Achieve an Open NAT type

Since the ‘Server snapshot error’ in Call of Duty: Vanguard is most likely beyond your control, the best thing you can do at this point is ensure that your NAT (Network Address Translation) is Open.

Note: NAT is a metric that is used to determine how easy it is for your machine to connect to other players (and vice-versa) when playing an online game.

If your NAT type is closed, you can expect this error to occur much more consistently as you’re having trouble maintaining the connection with other people that are in the same lobby as you.

Keep in mind that even though Activision uses dedicated servers for matchmaking, the game offloads much of the actual grunt work to the bandwidth of the players. This is why ensuring that you have an Open NAT type is so important.

Depending on the platform that you’re experiencing this issue on, the steps of figuring out if your NAT is Open or Close will be different.

We’ve created 3 separate sub guides that will show you how to see if your NAT type is Open or closed.

Follow the one that is applicable to your platform of choice

Check the NAT type on Xbox One or Xbox Series S/X

To check your NAT type on your Xbox console, you’ll need to access the Network settings menu and check the Current Network Status.

  1. On your Xbox One or Xbox Series X/S console, press the Xbox button to bring up the guide menu.
  2. From the Guide menu, go to the System tab and access the All Settings menu.
    Accessing the Settings menu on Xbox

Note: If the investigation has revealed that the NAT type is set to Closed, move down to the ‘How to Open NAT section’.

Check the NAT type on the PC

If you’re experiencing the issue while playing the game from a PC, you’ll need to open up the Xbox Console Companion app and access the Network settings to view the current state of the NAT type.

Here’s what you need to do:

Note: If the Xbox Console Companion app is not downloaded on your PC, you can download it from the official page.

  1. Press the Windows key and use the search function to find the ‘Xbox console companion‘ app.
  2. From the list of results, click on Xbox Console Companion to open up the application.
    Open up the Xbox Console Companion app
  3. Once you’re inside the Xbox Console Companion app, click on the gear icon (bottom-left corner), then click on Network from the menu at the top.
    Access the Network tab of the Xbox Console companion app
  4. Wait until the network is analyzed, then check the status of the NAT under NAT Type.
    Check the NAT type

    Note: If it’s set to Closed or Moderate, follow the steps inside the ‘How to Open NAT’ below.

Check the NAT type on Playstation 4 and Playstation 5

If you’re experiencing this issue on Playstation 4 or Playstation 5, you’ll need to access the Network settings and open the View Connection Status menu.

Here are the full instructions:

  1. From the main dashboard of your PlayStation system, access the Settings menu.
    Accessing the PS5 settings menu
  2. From the Settings menu that just appeared, access the Network menu.
    Access the Network menu
  3. Inside the Network menu, access the View Connection Status section and check the status of your NAT.
    Check the NAT type on PS4 or PS5

    Note: If the displayed NAT type is different from Type 2, follow the steps below to open your NAT type.

Open the NAT from your Router settings

If the investigations you performed above have revealed a closed NAT, chances are the ports used by Call of Duty Vanguard are not properly forwarded. In this case, you should access your Router Settings and enable UPnP (Universal Plug and Play).
