Investigating into the issue we have found out there can be one of the following reasons for the Error Code 224003: Before you proceed to the solution you need to make sure that your Web Browser is up-to-date, there is no connectivity issue on your system.

Turn Off your Add-ons and Extensions

It has been observed that certain kinds of Extensions and Add-ons particularly those that disable ads from being displayed in the browser can cause the video to be blocked. The main reason is that most sites these days rely on ads to continue providing free services to the users. These sites first perform a check to ensure that their ads are being displayed to the user. In case the ad is somehow blocked then the website does not allow the video to be played.

For Chrome

Turn Off Hardware Acceleration

Many browsers use hardware acceleration to improve the browser’s performance. Hardware acceleration allows your CPU to offload some page-rendering and loading tasks and assign them to your system’s GPU. But sometimes this feature can interfere with other tasks like video playback. Here, we will turn off the Hardware Acceleratio and see how it goes.

Update the Browser to the Latest Build

A user may encounter the error code 224003 if the browser in use is outdated as its incompatibility with the website may not let the website load the required video codecs. In this case, updating the browser to the latest build may clear the error. For illustration, we will discuss the process of updating the Chrome browser on a PC.

Enable History of the Browser

If the browser is configured to not save its history, then that may not let the problematic website fully authenticate a user’s credentials as the browser is not allowing the website to store its cookies on the client machine. In this context, enabling the history of the browser may resolve the issue. For elucidation, we will discuss the process for the Firefox browser.

Clear the Browser’s Cookies and Cache

If the browser’s cookies or cache is corrupt, then that may result in the 224003 error as this corruption does not allow the website to properly authenticate the user’s credentials. In this case, clearing the browser’s cookies and cache may clear the error at hand. For illustration, we will discuss the process for the Chrome browser and Animeflix website. Before proceeding, make sure to note down essential info (like website logins, etc.) of the browser.

Try Another Browser

A website may show the error code 224003 when streaming a video if the browser in use is not compatible with the website and due to this incompatibility, the website fails to access the essential video codecs on the user’s system. In such a case, trying another browser to stream the video from the problematic website may resolve the issue.

Try a VPN or Use Another Network

If the ISP is hindering the traffic between the website and your device in a way that is making the website’s data packets un-parse-able on the server or client-side, then that may result in the error code 224003. Here, trying a VPN or using another network may clear the video file playing error.

Disable Private Address of iPhone

Apple has equipped its iPhone with a security feature in the form of the Private Address. This feature enables a user to save his private data on an unfamiliar or public Wi-Fi. This Private Address feature may not let a website stream the problematic video as it limits the website’s access to essential video codecs (“thinking” it is unsafe), which may result in the video file cannot be played error code 224003. In this case, disabling the Private Address in the iPhone Settings may clear the issue. 

Disable the System or Network Firewall

If the system or network firewall is limiting the website traffic to the user’s system or device, then that may cause the file cannot be played error as the website fails to load its content on the user’s device. In this case, disabling the system or network firewall may clear the error code 224003. For illustration, we will discuss the process of disabling ESET Internet security (antivirus and firewall) on a Windows PC.   Warning: Advance with utmost care and at your own risk as disabling the system or network firewall may expose the system, data, and network to threats.

Install Media Packs for Windows N

Windows N is a fully functional Windows variant that misses some of the media technologies. If the error code 224003 is occurring on a Windows system with Windows N as its operating system, then the missing media technologies on the system could be the root cause of the issue as the essential video codecs to stream the problematic video are missing. In this scenario, installing the Media Packs for Windows N may solve the problem. A user may use the official Microsoft documentation to install media packs for the particular Windows OS but for illustration, we will discuss the process for Windows 11 N version. If none of the above worked, then a user may contact the support of the problematic website as the problem could be with the video stream of the website.
