What's the net::ERR_HTTP2_PROTOCOL_ERROR about? 🤔

So you're working on a website, and suddenly you encounter a pesky error on Google Chrome: net::ERR_HTTP2_PROTOCOL_ERROR 200. You're not alone! Many developers have faced this issue, particularly when accessing websites over HTTPS. It seems to interfere with the proper execution of JavaScript and may cause certain elements to fail to load. But fear not, we're here to decode this error for you and provide easy solutions. Let's dive in! 💪

Understanding the Error 📚

The net::ERR_HTTP2_PROTOCOL_ERROR is specific to the HTTP/2 protocol and indicates a problem during the communication between the client (your browser) and the server. It represents a failure in the HTTP/2 protocol implementation, which can prevent the rendering of web pages and the execution of JavaScript.

Common Triggers 🔍

Based on user reports and investigations, we've identified a few common triggers for this error:

1. HTTPS Access: The error seems to be frequently associated with accessing websites over HTTPS. It doesn't occur when accessing the same website over HTTP.

2. Specific Browsers: This issue appears to be more prevalent in Google Chrome, while users have reported that it works fine on other browsers such as Firefox and Edge.

3. Recent Chrome Releases: The error seems to have emerged in more recent releases of Google Chrome (v75+), while it didn't occur in earlier versions (e.g., v64.X).

Possible Causes 🤷‍♂️

While the exact cause of the net::ERR_HTTP2_PROTOCOL_ERROR is not well-documented, here are some possible explanations based on user experiences:

1. Server Response: It's worth considering if the server response plays a role since the error message includes the 200 status code. However, users have observed that pages returning a 404 or 500 status code don't trigger the error, making this connection uncertain.

Easy Solutions 💡

Now, let's talk about some easy solutions to resolve the net::ERR_HTTP2_PROTOCOL_ERROR:

1. Clear Browser Cache: Start by clearing your browser cache, as this can resolve certain issues caused by cached data.

2. Disable Experimental Features: In Chrome, type chrome://flags in the address bar and hit Enter. Then, search for "HTTP/2" and disable the experimental features related to it.

3. Disable Chrome Extensions: Some Chrome extensions might interfere with the HTTP/2 protocol. Disable all extensions and see if the error persists.

4. Try a Different Browser: If possible, test your website on different browsers such as Firefox or Edge to see if the error occurs there. This can help isolate the issue.

5. Reach Out to the Server Admin: If you don't have control over the server configuration, contact the website's server administrator or hosting provider to investigate further.
