php curl http2 laravel http-client PHP

I've been banging my head against this for hours. I'm working with an scenario with cURL in PHP 8.1 when making HTTP/2 requests from my Laravel application. Despite having the `http2` option enabled, the server seems to be responding as if it's using HTTP/1.1. I've configured my cURL options as follows: ```php $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://example.com/api/data'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0); curl_setopt($ch, CURLOPT_HEADER, true); $response = curl_exec($ch); $behavior = curl_error($ch); curl_close($ch); ``` When I run this code, I expect to see an HTTP/2 response, but when I check the response headers, it shows `HTTP/1.1 200 OK`. Additionally, `curl_getinfo($ch, CURLINFO_HTTP_CODE)` returns 200, which suggests the request was successful, yet the protocol version doesn't match. I have confirmed that the server does support HTTP/2 as I can see it in the headers when using other clients like Postman. I've tried updating my cURL version and verified that the cURL extension is enabled in my PHP configuration. The output of `phpinfo();` shows `cURL support enabled`, and I have the `HTTP2` feature available. Is there a specific configuration in Laravel or cURL that might be preventing HTTP/2 from being used, or could this be a potential bug in PHP 8.1? Any insights would be greatly appreciated! Has anyone else encountered this?
