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);
