What happened
An HTTP request was sent to the HTTPS port with a 400 Bad Request response, suggesting that an error occurred in the request. This is not uncommon, but it's essential to understand why.
NGINX and web server configuration
Nginx is a popular HTTP server software that can also be used as a reverse proxy. In some cases, it may not handle HTTP requests correctly, leading to 400 Bad Request responses.
Common solutions
To fix the issue, you can try the following:
- Check your Nginx configuration
- Review your web server logs to identify any errors or issues
- Consider using a more robust reverse proxy like HAProxy or NGINX's built-in support for HTTP requests
