Solution :
I had also faced the same problem in the past.
Please follow bellow instructions to resolve the issue
Please edit the /wp-includes/class-http.php file – change SSL as noted in bellow code example
‘decompress’ => true,
// ‘sslverify’ => true
‘sslverify’ => false,
‘sslcertificates’ => ABSPATH . WPINC . ‘/certificates/ca-bundle.crt’,
‘stream’ => false,
‘filename’ => null,
‘limit_response_size’ => null,
);
