Why Does My Chrome Browser Show a 'net::ERR_HTTP2_PROTOCOL_ERROR' Only on HTTPS Websites?

Addressing the "net::ERR_HTTP2_PROTOCOL_ERROR" Encountered While Accessing a Website

Problem Description:

Utilizing Google Chrome, users may encounter a "net::ERR_HTTP2_PROTOCOL_ERROR" 200 error when accessing a website via HTTPS. This error appears to affect JavaScript execution, as exemplified by an integrated Twitter feed failing to load.

Potential Causes and Observations:

• Occurs only when accessed via HTTPS, suggesting a relationship to the protocol.
• While the error is persistent on Chrome, it is absent on other browsers like Edge and Firefox.
• The error does not trigger on pages with a 404 error code.

Header Analysis:

A comparison of the HTTP headers from Chrome and Firefox revealed differences. Chrome displayed a 200 status code, while Firefox showed no errors.

Connection Status:

Using the chrome://net-export/ and https://netlog-viewer.appspot.com tools, it was discovered that the request ends with a RST_STREAM. As described in documentation, this behavior occurs when the client (in this case, the browser) aborts the request.

Possible Culprit:

Based on the aforementioned behavior and the lack of consistent errors, it is speculated that the browser may be the root cause. However, this conclusion conflicts with the absence of the error on pages with 404 headers.

Resolution:

No disk space left on the web server.
