Many users reported experiencing an Amazon App CS11 error while using various Amazon applications (Amazon Prime, Amazon shoppers, etc.). The error message mainly appears on mobile devices like iPhones and iPods, but also appears on other platforms such as Android.

The Amazon App CS11 error is a problem that can occur when you are trying to download or update an app from the Amazon Appstore. This error can prevent you from downloading or updating apps, and it can also prevent you from opening the Amazon Appstore.

There are several ways to fix this error. In this article, I will show you the best methods that can help you to fix this issue in minutes.

What is the Cause for this “Amazon App CS11 Error”?

Along with the Amazon server outages caused by political events, the following are notably responsible for causing Amazon OSCS 11 error messages:

  • Outdated Amazon App: If the Amazon Application Update setting is not updated on the most recent build, Amazon Servers may deny the application access to your device, resulting in the CS11 error message.
  • Corrupt Amazon App Installation: If the Amazon app software is corrupted, the program may generate an error, such as a CS11 error, if certain app modules are inaccessible or not executable.
  • Network Firewall Restrictions: If the right network firewall (such as PiHole) prevents Amazon from gaining access to its servers (such as Amazon Shoppers), the Amazon app can present you with an error message.

Method 1: Update the Amazon App to the Latest Build

When it comes to Amazon App, there are two types of users: those who have updated the app and those who have not. There are many reasons why you should update the Amazon App on your iPhone.

Method 3: Disable Network Firewall or Add Amazon Exceptions to the Firewall

If the network firewall (such as PiHole) blocks Amazon Computing Services’ access to the required domains or servers, you may encounter the Amazon application CS11 on the Amazon app. In such a situation, turning off the network firewall or permitting exceptions to the Amazon domains for the network firewall may fix the issue.

  • When the Command Prompt window opens, run the following command:
pihole
  • Execute the following command at the Command Prompt once the PiHole interface has been launched.
pihole disable
  • If PiHole is disabled, launch the troublesome Amazon app and then hopefully, it is clear from CS11. If so, then add the culpable Amazon domains to the exclusions list of PiHole. Ordinarily, the aspiring curious domains should be added.
aax-us-east.amazon-adsystem.com   
fls-na.amazon.com  
amazon-adsystem.com
  • Enable PiHole by clicking the following within the command line. Users will see the popup when Claimed is enabled.
pihole enable
