The error nginx: [emerg] invalid parameter "quic"

The error nginx: [emerg] invalid parameter "quic" usually means that the Nginx version you're using does not have support for QUIC and HTTP/3, or that it's not compiled with the necessary modules and libraries.

Here’s a checklist to troubleshoot and resolve the issue:

---

1. Check Nginx Version

QUIC and HTTP/3 support were introduced starting with Nginx 1.25.0 (released in June 2023). Ensure your Nginx version is up-to-date.

To check your version:

If your version is older than 1.25.0, you'll need to upgrade.

---

2. Ensure Nginx is Built with QUIC Support

Nginx does not enable QUIC and HTTP/3 by default. It requires specific modules and libraries:

• OpenSSL 1.1.1 or later (or a compatible fork like BoringSSL).
• The Nginx binary must be compiled with the --with-http_v3_module option.

You can check your build configuration using:

Look for the --with-http_v3_module option in the output. If it’s missing, you’ll need to compile Nginx manually with QUIC support.

3. Install Required Dependencies

To compile Nginx with QUIC:

• Install a supported version of OpenSSL or BoringSSL.
• Compile Nginx with the necessary flags:
  bash

   

  ./configure --with-http_v3_module --with-openssl=path/to/openssl

---

4. Check Your Configuration

Ensure your nginx.conf contains the proper directives to enable QUIC. A minimal QUIC configuration might look like this:

---

5. Restart Nginx

After updating the configuration, restart Nginx to apply the changes:

---

6. Verify QUIC Support

You can verify QUIC support using tools like:

• HTTP/3 Test
• Command-line tools like curl (with HTTP/3 support):
  bash

   

  curl -I --http3 https://your-domain.com
