400 The Plain Http Request Was Sent To Https Port

When a request is sent to an HTTPS port, the browser attempts to negotiate SSL/TLS encryption. However, in certain cases, the server may not send the SSL certificate, or it may be corrupted, resulting in a plain HTTP response.

• A 400 error is typically received when the client (browser) cannot find the expected resource or does not have permission to access it.
• In some cases, the server may respond with an HTTP 301 Moved Permanently or 403 Forbidden response without sending the SSL certificate, leading to a plain HTTP response.

This is often due to issues with the server's configuration, SSL/TLS certificates, or network connectivity. If you experience this error when accessing websites in Melbourne, it may be worth checking your local network settings and ensuring that the HTTPS port is correctly configured on the server hosting the website.

Example Use Case

For example, if a user attempts to access a website hosted on an Australian server that uses the standard HTTP protocol (i.e., no SSL/TLS encryption), they may receive a plain HTTP response with a 400 error code. In this case, the correct behavior would be for the server to respond with an HTTPS URL and negotiate SSL/TLS encryption.
