http_code 0 with Redhat php curl

I can use lynx to access a website from the server fine. When I try to access the same website with a php curl instruction I get http_code=>0 from curl_getinfo($ch);
The same php code on another redhat server in the same data centre works fine. I have admin access to the server.

I have tried php 7.4 and php 8.0
curl is enabled when I call phpinfo();
I am unsure how to debug this error!

It is RHEL 8.8

This is the output from curl_getinfo($ch);

Array ( [url] =>
https://…..
[content_type] => [http_code] => 0 [header_size] => 0 [request_size] => 0 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 0.055895 [namelookup_time] => 0.105978

    I can use lynx to access a website

    Probably you can’t access it via curl cli because of the cookies.

    # err
$ curl https:// --verbose
# suc
$ curl https:// 
      --verbose 
      --cookie="/tmp/cookie.txt" 
      --cookie-jar="/tmp/cookie.txt"

    PHP representation

    $cookieFile = '/tmp/cookie.txt';
$ch = curl_init($url);
curl_setopt_array($ch, [
   CURLOPT_COOKIEJAR => $cookieFile,
   CURLOPT_COOKIEFILE => $cookieFile,
   // other options
]);
curl_exec($ch);
curl_close($ch);
