The Warzone "Puget Altus" error is a network error in the game. It occurs when the user's system is unable to connect to the game's servers. This causes players to get stuck in the login stage and they are unable to even access the Call of Duty HQ. The error can be both server-sided as well as client-sided. However, if it is the prior, then there's little players can do to resolve it.

That said, if the error lies on the user's end, then there are a few possible fixes that can resolve the issue completely. Hence, in this article, we will take a closer look at some of the potential fixes for the Warzone "Puget Altus" error.

How to possibly fix the Warzone "Puget Altus" error?

Before you begin with the possible fixes for the Warzone "Puget Altus" error, make sure to check the status of Warzone servers. If the servers are online and no issue has been reported, then you may proceed with the fixes for the Warzone "Puget Altus" error:

Restart your router

The first thing that you should do is restart your router. While that may not sound like much, a proper reboot of the router can fix a host of network issues. Properly rebooting the router requires removing all the power cables from the device for at least 10 seconds. This will reset the cache. Once that is done, you can plug it back in and see if the error goes away. If it doesn't, check out the fix below.

Allow the game through the Firewall

Sometimes your Anti-virus can block the game from accessing the internet and this can cause the Warzone "Puget Altus" error. Hence, it is advised to check your anti-virus Firewall rules to see if the game is blocked. If you aren't using any third-party software, then Windows Firewall will be in charge, and here's how you can change your Firewall rules:

Open your 'Control Panel'.
Select 'System and Security'.
Now, go to 'Windows Defender Firewall'.
From the left panel, select 'Allow an app or feature through Windows Defender Firewall'.
Select 'Change Settings'.
From the list of apps, look up 'Call of Duty Core' and ensure that the all boxes next to it are checked.

Doing so will allow the game to access the internet and the error should disappear.

Flush DNS Cache

Allowing the game through your Firewall didn't resolve the Warzone "Puget Altus" error, it is recommended to flush your DNS cache. Here's how you can do it easily on Windows 10 and 11:

Use the search to look up 'Command Prompt' and launch it.
Type in "ipconfig /flushdns" (without the quotes) in the CMD window.
Hit 'Enter' to run the command.

That's it. If the process was successful, you will be presented with a message that states "Successfully flushed the DNS Resolver Cache."

Use a different ISP

This is more of a diagnostic step rather than a fix. If you are still unable to access the game, it is recommended to use a different ISP and see if Warzone allows you to access the servers. If it does, the issue lies with your ISP and you should get in touch with them to resolve the issue.

If you don't have a second connection at home, you can use your mobile hotspot as a secondary connection for this diagnosis.

That covers all the known possible fixes for the Warzone "Puget Altus" error. If the issue persists despite implementing the abovementioned fixes, it is recommended to contact the Activision Support team for further assistance.
