How can I troubleshoot 'error while reading line from the server' when making HTTP requests in Laravel?

To troubleshoot this, first check your network connection. If you're making requests to an external API, verify that the API endpoint is reachable and responsive. Increase HTTP client timeouts in your Laravel configuration (e.g., `config/services.php` for Guzzle defaults) if the server is slow to respond. Also, inspect the server logs for any errors that might be occurring on the remote end.
