One of the most frequent problems in Call of Duty: Modern Warfare 3 is an annoying bug “WOLTERS — INDIANA”. In fact, it resembles the Hueneme Concord bug: the connection is disconnected, the game does not allow online services and completely blocks access to online matches. The error most often pops up when launching the application COD HQ.
Although there is no exact reason for its appearance yet, the players assume that it is either due to unstable servers with an influx of online traffic, or a weak Internet connection. But there is no reason to panic — there are several ways to quickly deal with the problem and return to the battlefield.

How to fix the Wolters Indiana bug in MW3
Restart your game or device
Start with a simple one. Close and reopen Call of Duty — sometimes that’s enough. If it doesn’t help, do a full reboot of the device: turn off your PC, PlayStation, or Xbox, unplug the power cord, wait a couple of minutes, and turn it back on. After that, try logging back into Modern Warfare 3.
Such a “hard restart” often solves temporary failures — the system is updated, and many errors disappear on their own. If the problem persists, you should check the connection or check the status of the servers. Take a look at the official forums or Call of Duty support — they usually warn you about failures and technical issues.
Restart the router
If restarting the game and the device did not help, pay attention to the Internet. Stable communication is critically important for online shooters. Turn off the router, unplug it from the wall outlet, wait a couple of minutes and turn it on again. After that, try to launch the game again.
If the error still appears, do a speed test. It will show the download speed, kickbacks, and ping. If the results are low, try to move the router to a better location or contact the provider. Sometimes updating the device’s firmware also helps — manufacturers regularly release updates that increase stability.
But it’s possible that it’s not about your Internet, but about the MW3 servers themselves. In this case, it remains only to wait for the developers to fix the problem.
Check the status of Call of Duty servers and social networks
To find out where the reason lies, visit Activision Online Services. There is a status indicator for the servers: green means that everything is working as it should, but yellow or red will indicate problems on the developers’ side.
If the servers are down, all that remains is to wait. And to keep up to date, keep an eye on Call of Duty Updates on X (Twitter) — they promptly publish information about bugs, technical work, and bug fixes.
Reinstall the COD HQ application
If the bug still prevents you from logging into the game, try clearing the COD HQ cache. In the application settings, find the item related to storage or temporary files and reset them. After that, restart the application and check the login.
Also, make sure that you have the latest version of the app installed — updates often contain bug fixes. Close unnecessary programs running in the background: sometimes they interfere with the normal operation of COD HQ.
If none of the above has helped, it’s time to contact support.
Send the report to Activision Support
When the other methods didn’t work, write to Activision Support. Specify all the details: the description of the error, the code, the device and the steps at which it appears. The more accurate the report is, the sooner the experts will figure it out.
It may take a while to get a response — there are a lot of complaints, and they are sorted by priority. But you can be sure that the developers are interested in players entering MW3 without any problems, and they will definitely take care of your situation.
