Netflix is the world’s leading media streaming platform that offers its users access to the biggest libraries. Netflix app is available on Android and iOS platforms and is accessible from a browser on a computer. Although Netflix provides a stable service, users in some cases may encounter issues when accessing it. In this article, we are going to address Netflix Error codes M7121-1331-P7 and M7111-1331-4027.
The Netflix Error codes M7121-1331-P7 and ‘M7111-1331-4027 usually occur if either the browsers fail to meet the playback criteria or if the cache contains corrupted data prevents playback. In some situations, these error codes also occur when the Netflix server is offline.
Before following any of the below-recommended troubleshooting steps, it is best to restart your computer. This refreshes the OS and removes any corrupted temporary data that may cause the error.
Use a browser that supports HTML5
Use only reliable and popular browsers, such as Chrome, Firefox, Safari, and Edge, when accessing Netflix. These browsers are officially supported, and HTML5 is enabled in these browsers. HTML 5 is the modern markup language and is used by nearly all popular streaming services. Make sure to enable it before accessing Netflix if disabled manually.

Disable Chrome extensions
