Why Am I Getting the net::ERR_HTTP2_PROTOCOL_ERROR in Chrome?
Understanding the net::ERR_HTTP2_PROTOCOL_ERROR Error
The net::ERR_HTTP2_PROTOCOL_ERROR is a relatively new web error that can occur when accessing websites using HTTPS in Google Chrome. It is characterized by error code 200, indicating that the server returned a successful response, but the client (Chrome) encountered a problem with the protocol.
This error is often associated with JavaScript execution issues, preventing widgets or third-party scripts from loading properly. A common scenario is when a Twitter feed integrated via HTTPS does not load, and the console displays the ERR_HTTP2_PROTOCOL_ERROR.
Possible Causes of the Error
While the error is not well-documented, possible causes include:
- Server header issues (specifically, a header with code 200)
- Lack of disk space on the web server
- Problems with HTTP/2 protocol implementation in Chrome
Troubleshooting Steps
To resolve the net::ERR_HTTP2_PROTOCOL_ERROR, try the following steps:
- Check server headers: Inspect the HTTP header of the affected resource. Ensure it is properly formatted and includes a valid certificate.
- Verify disk space: Make sure that the web server hosting the site has sufficient disk space. Lack of space can prevent proper execution of HTTP/2 requests.
- Update Chrome: Keep Chrome up-to-date. New releases may address protocol-related errors.
- Disable QUIC protocol: In Google Chrome's settings, disable the Experimental QUIC protocol. While unrelated to HTTP/2, QUIC issues can sometimes cause this error.
- Try other browsers: Temporarily switch to another browser (e.g., Firefox or Edge) to see if the issue persists.
Example Case: Disk Space Issue
In one reported case, the net::ERR_HTTP2_PROTOCOL_ERROR occurred due to insufficient disk space on the web server. Once the disk space was freed, the error disappeared.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
How do you handle exceptions effectively in PHP (try, catch, finally, throw)?
Apr 05, 2025 am 12:03 AM
In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.
Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error).
Apr 08, 2025 am 12:03 AM
There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.
What is the difference between include, require, include_once, require_once?
Apr 05, 2025 am 12:07 AM
In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.
