Why Does Chrome Throw a 'net::ERR_INCOMPLETE_CHUNKED_ENCODING' Error?

Root Cause of "net::ERR_INCOMPLETE_CHUNKED_ENCODING" Error in Chrome

The "net::ERR_INCOMPLETE_CHUNKED_ENCODING" error, characterized by truncated files, hanging pages, and pages failing to load, can be attributed to a specific issue in Chrome's request handling. This error occurs when the browser does not receive complete chunks during a chunked HTTP transfer.

Solution: Investigating Client-Side Causes

Despite extensive server-side investigation, the root cause of the error was ultimately identified as a conflict with the user's anti-virus software. Disabling the Real-Time protection in ESET NOD32 ANTIVIRUS 5 resolved the issue, and similar behavior was observed with Real-Time protection enabled in Kaspersky anti-virus.

Implications for Server Configuration

Although the solution to this specific error lies in disabling anti-virus protection, it is essential to note that forcing HTTP 1.0 as a workaround is not a sustainable solution. Sever configuration should maintain HTTP 1.1 compatibility, allowing for improved performance and security.

Prevention and Troubleshooting

To prevent the "net::ERR_INCOMPLETE_CHUNKED_ENCODING" error and similar browser-specific issues, it is recommended that users:

• Regularly update their anti-virus software.
• Consider disabling Real-Time protection when experiencing browser issues.
• Enable Incognito or Private Browsing mode to isolate browser settings and extensions as potential causes.
• Monitor the browser's developer console for errors and warnings.
