How can I check if my hosting server supports HTTP/3?

Asked on Sep 11, 2025

Answer

To check if your hosting server supports HTTP/3, you can use online tools or command-line utilities that test for HTTP/3 support by connecting to your server. These tools will indicate whether your server is configured to handle HTTP/3 requests.

Example Concept: Use an online tool like "HTTP/3 Check" or a command-line utility like "curl" with the appropriate flags to test your server's HTTP/3 support. These tools send a request to your server and check if it responds using the HTTP/3 protocol, indicating that your server is configured correctly for HTTP/3.

Additional Comment:

HTTP/3 is the latest version of the HTTP protocol, designed to improve speed and security over previous versions.
Ensure your server software (e.g., Nginx, Apache) and TLS library (e.g., OpenSSL, BoringSSL) are updated to the versions that support HTTP/3.
Check your server's configuration files to ensure HTTP/3 is enabled, as it may not be by default.
Consider using a CDN that supports HTTP/3 if your hosting provider does not yet support it directly.
