Make request working with newer curl versions

[EmanueleCoppola]

I'm having some issues with a newer curl version (PHP 8.1 and CURL 7.81.0 on Linux) It seems like it's using HTTP2 by default, so it doesn't work with your api anymore. I haven't investigated further but by adding this line it works fine again.

Could you please get a bit deeper into the issue? I actually couldn't investigate more.

https://curl.se/libcurl/c/CURLOPT_HTTP_VERSION.html

Default Since curl 7.62.0: CURL_HTTP_VERSION_2TLS

Before that: CURL_HTTP_VERSION_1_1
