The Warzone "Lost connection to Host" error has been bugging players for a while now. What makes this error more annoying is that it happens in the middle of a match. This not only results in players losing out on progress and a potential win but also leads to the abandonment of their teammates, leaving them stranded in a disadvantageous situation.

The error can be both server-sided as well as client-sided. If it is an issue with the game's server, then there's little that players can do. However, if its client sided, it can be resolved pretty easily.

Hence, in this brief guide, we'll take a closer look at some of the possible fixes for the Warzone "Lost connection to Host" error.

NOTE: The fixes mentioned below may not prove successful to everyone. However, they are worth trying until the developer releases an official patch.

How to possibly fix Warzone "Lost connection to Host" error

Before you start with the fixes for the Warzone "Lost connection to Host" error, it is recommended to check the status of Call of Duty servers. If they are online and no issues are reported, then you can proceed with the fixes.

Here are some of the possible fixes for the Warzone "Lost connection to Host" error:

Restart your router

If your router has been turned on for a while, like a day or so, it is recommended to restart your router. A proper reboot will clear your router's cache and this holds the potential to rid of a host of network-related issues.

Hence, if you haven't already, it is highly recommended to do a proper restart. To do so, remove all the power from the router for at least 10 seconds and then plug the cables back in. This will reset the cache.

If you are still facing the Warzone "Lost connection to Host" error, you should try flushing your DNS cache. To do so, follow these steps:

Press 'Win+R' and type in 'cmd' in the Run box.
Next, in the CMD window, type in "ipconfig /flushdns", without the quotes.
Finally, hit 'Enter'.

That's it. Doing so will clear your DNS cache and you should be able to play the game again without encountering the Warzone "Lost connection to Host" error. If this, however, didn't fix the issue, check out the next solution below.

Turn off On-Demand Texture Streaming

If you have On-Demand Texture Streaming turned on and don't have the best internet, it is recommended to turn it off immediately. Here's how you can do it:

Launch Warzone.
Go to the 'Settings' tab and find the 'Graphics' settings.
Navigate to 'Quality' and locate the 'Texture & Details' section.
Find' On-Demand Texture Streaming' and then turn it off.

This setting, when turned on, downloads texture files in the background while you are playing the game. This can have adverse effects on your connection to the game's servers if you don't have an internet connection with high bandwidth. That is why should always keep it turned off unless you want the best visuals or have a strong network.

Use a different ISP

This isn't a direct fix but more of a workaround to help you identify the cause of the problem. If you have an additional internet connection at your home, you should try playing the game using it.

Alternatively, you can also try playing using your mobile hotspot. If you can play Warzone on a different connection without issues, it means that your primary ISP is to be blamed. In that case, you should contact your ISP for assistance.

That covers all the possible fixes for the Warzone "Lost connection to Host" error. If the problem persists despite implementing the above steps, it is advised to get in touch with the Activision Support team for further help with the Lost connection to Host error.
