How to Fix Error Status Bamberga in COD Infinite Warfare

The Status Error Bamberga is encountered by Call of Duty Infinite Warfare users when trying to join a friend’s online session. This problem is reported to occur on both consoles (PS4, Xbox One) and on PC.

COD Modern Warfare Status Error Bamberga

As it turns out, there are several different causes that might be responsible for the apparition of this error code:

  • Game inconsistency – If you’re seeing this error on PC, it’s possible that you’re only dealing with a superficial inconsistency that can be resolved with a simple game restart. This is typically reported to work for Windows users in instances where the game has been in idle mode for a long period.
  • NAT is closed – The most common cause that will trigger this error code is an instance in which the NAT (Network Address Translation) is closed. If this scenario is applicable, you should be able to fix the problem either by forwarding the ports manually or by enabling UPnP (in your router settings) if your browser supports it.
  • TCP / IP Inconsistency – If you’re encountering this issue on a console (Xbox One or PlayStation 4), it’s also possible to face this problem due to the fact that your console is retrieving the wrong network information so the connection cannot be established. In this case, you should be able to fix the problem by using a static IP.

Method 1: Restarting the Game

If the frequency of this error is rare, one temporary workaround that a lot of affected users have used successfully is to simply restart the game. This fix was confirmed to work on PC, Xbox One, and PlayStation 4.

Simply exit the game completely (close it rather than putting it in the background), wait for a couple of seconds, then launch it again.

This was enough to fix the problem for a lot of different users, but for some, it took a second try. If you already did this and you’re still seeing the same error, move down to the next potential fix below.

Method 2: Opening NAT

If a simple restart didn’t do the trick, it’s very likely that you’re encountering the Bamberga status error with COD Infinite Warfare due to an inconsistency with the Network Address Translation. This is the most important metric that will determine if the game server accepts the connection to your machine or not.

If your NAT is closed, you will NOT be able to connect to other players when playing Call of Duty Infinite Warfare.

If you’re facing this error on PC or Xbox One, you should start by checking your NAT Type on your platform of choice. Of course, depending on the platform where you’re playing the game, this procedure will be different.

Because of this, we’ve created 3 separate sub-guides (A, B & C) that will walk you through the process of checking if the NAT is closed on open on Xbox One, Playstation 4, and PC. Follow the guide that is applicable to your platform of choice.

A. Checking the NAT on PC

  1. Press Windows key + R to open up a Run dialog box. Next, type ”ms-settings:gaming-xboxnetworking” inside the text box, then press Enter to open up the Xbox Networking tab of the Gaming Settings app.

  2. Once you’re inside the Xbox Networking tab, wait for the initial investigation to complete, then check the NAT Type once the results are displayed. If the Nat Type shows at ‘Closed’ or ‘Teredo is unable to qualify‘, you can conclude that the problem is indeed occurring due to your NAT.

    Note: You can also attempt to fix the issue automatically by clicking the Fix it button, but this will only work as long as the problem is not being caused by your router.

  3. If you confirmed that the NAT Type is Closed or Inconclusive, move down to the FIX section where we’ll show you how to open your NAT from your router settings.

B. Checking the NAT on Xbox One

  1. On your Xbox One console, press the Xbox button on your controller and bring up the guide menu.
  2. From the Guide menu System tab and access the Settings menu.

  3. Once you’re inside the Settings menu, go to the Network tab and access the Network settings menu.

  4. From the insides of the Network settings menu, look under the Current Network Status and see if the NAT Type field is displayed as Open or Closed.

  5. In case the NAT Type shows as closed, move down to the FIX section for instructions on how to open the NAT type from your router settings.

C. Checking the NAT on PlayStation 4

  1. On the main dashboard of your PS4 system, go to Settings and access the Network menu. Once inside, tap on the View Connection Status.
    View Connection Status
  2. Wait for the investigation to complete, then check the NAT that is displayed on the next screen. You will have one of the following 3 NAT Types:
    NAT Type 1 - Open 
    NAT Type 2 = Moderate
    NAT TYpe 3 = Strict Closed

    Note: If your NAT type is 1 or 2, it’s very likely that the problem is NOT related to your NAT. In this case, you’re probably dealing with a different type of inconsistency.

  3. If the investigation has revealed that you’re actually dealing with a strict NAT, follow the guide below to ensure that your NAT is open from your router settings.

Enabling UPnP To Open NAT

If you previously confirmed that you’re indeed dealing with a closed NAT and that’s most likely the problem causing the Bamberga error, you should be able to fix the problem swiftly by accessing your router settings and enabling Universal Plug and play.

The vast majority of users will support this feature since it has become the industry standard for some years now. But if you’re using an older router model is more than 5 years, old, it’s possible that it’s not equipped to support UPnP – in this case, you can either attempt to update your router firmware or you can move down to the next potential fix below for instructions on opening the ports required by COD Infinite Warfare manually.

Method 3: Forwarding the Ports Manually

In case the investigations you previously did have revealed that you’re dealing with a NAT issue but you couldn’t enable UPnP because you’re using an older router, the only fix that will finally allow your to circumvent the Bamberga status error in COD Infinite Warfare is to manually forward the ports used by the game in your router settings.

If this scenario is applicable to your particular situation, follow the instructions below to forward the ports used by COD Infinite Warfare manually:

  1. Open your default browser and type the following generic address inside the navigation bar and press Enter to access the router settings menu:

    Note: In the vast majority of cases, one of these addresses should get you to the login screen of your router. But in case your router address is different, here’s how to find the IP address of your router from any device.

  2. Once you get to the login screen, insert your custom credentials if you previously established any. In case it’s the first time you’re accessing this page, try the default credentials (admin or 1234 for both user and password) and see if you are able to login successfully.

    Note: In case you are not able to find the correct credentials, you can reset your router in order to revert back to the generic credentials.

  3. Once you finally manage to get past the initial login screen, look for the Advanced (Expert) menu and see if manage to find an option named NAT Forwarding (Port Forwarding or Virtual Server Ports)
    Port forwarding steps are slightly different for different routers
  4. Next, go ahead and forward the ports required by Call of Duty Infinite warfare depending on the platform where you’re playing the game on:
    PlatformTCP PortsUDP Ports
    PC3074, 27015-27030, 27036-270373074, 4380, 27000-27036
    PlayStation 480, 443, 1935, 3074, 3478-34803074, 3478-3479
    Xbox One53, 80, 307453, 88, 500, 3074, 3076, 3544, 4500
  5. Once you have successfully enabled every required TCP and UDP port according to your platform of choice, restart both your router and the console/PC and see if the issue is now resolved.

In case the same problem is still occurring, move down to the next potential fix below.

Method 4: Using a Static IP (Console Only)

In case you’re encountering this problem on a console, it’s possible that you’re seeing the Status Error Bamberga because your console is not actually using the correct TCP / IP settings. This will only happen in situations where the Internet Connection is filtered by a router or modem.

If this scenario is applicable, you should be able to fix the problem by forcing your console (Xbox One or Ps4) to use a static IP with the correct complementary settings.

If you’re not exactly sure on how to do this, follow the instructions below:

  1. On your computer, press Windows key + R to open up a Run dialog box. Inside the text box, type ‘cmd’ and press Ctrl + Shift + Enter to open up an elevated Command Prompt. When you’re prompted by the User Account Control, click Yes to grant administrative privileges.
    Running the Command Prompt
  2. Once you’re inside the elevated command prompt, type the following command and press Enter to get an overview of your current Internet connection:
  3. From the list of results, copy down the IPV4 address as you’ll use it later on your console.
    Fetching the IPV4 address
  4. Once you manage to obtain your IPV4 address, mover over to your PS4 console, and from the main dashboard, go to Settings > Network > View Connection status.
    View Connection Status

    Note: On Xbox one, you can view the same details by going to Settings > All Settings > Network > Network Settings.

  5. From the list of results, copy the Subset Mask, Default Gateway, Primary DNS, Secondary DNS, and the MAC Address.
  6. On your PS4, go to Set Up Internet Connection and choose Custom > Manual when you get to through the prompts to set up a static IP. use the IPV4 address that you copied at step 3, and then put the other options (Subnet Mask, Default Gateway, etc.) that you fetched at step 4.
    Setting the correct Internet connection

    Note: On Xbox One, go to Settings > General > Network Settings > Advanced Settings, then add the values you fetched above manually.

  7. Once you get to the other options (MTU, Proxy Server, etc.), leave them to their default values.
  8. Finally, access your router settings and then set the static IP and the IPV4 you previously copied from your PC and set to your PS4.
  9. Save the changes, then power cycle everything and see if the problem is now resolved.
