Error Fetching http headers

This library is really useful, but i am sort of stuck with this small part. I am using this library in laravel/framework: 8.75. But it shows below error

`exception: "SoapFault"
file: "artisaninweb\\laravel-soap\\src\\Artisaninweb\\SoapWrapper\\Client.php"
line: 189
message: "Error Fetching http headers"`

Can you please help me here.
