PHP cURL (Error: 28: Resolving timed out after milliseconds)

I'm trying to use cURL in php, but an error occurs, and nothing is returned in response:

* Hostname was NOT found in DNS cache * Resolving timed out after 5514 milliseconds * Closing connection 0 28: Resolving timed out after 5514 milliseconds 

The code is:

 <?php $url = "https://example.com/rest/checksms/9502ec34-5348-4096-838a-e7ac0cce9d74"; $cert_password = '123456789'; $curl = curl_init(); if ($curl === false) { throw new Exception(' cURL init failed'); } curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_CAPATH, "/home/redmine_dev/curl/client_smsgate-in.pem"); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_HTTPGET, 1); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 5); curl_setopt($curl, CURLOPT_TIMEOUT, 60); curl_setopt($curl, CURLOPT_VERBOSE, TRUE); curl_setopt($curl, CURLOPT_SSLCERTPASSWD, $cert_password); $result = curl_exec($curl); if ( ! $result) { print curl_errno($curl) .': '. curl_error($curl); } $result = curl_multi_getcontent ($curl); echo "\n".'Login OK'."\n".'[result ===8<===>'."\n".$result."\n".'<===>8=== result]'."\n"; curl_close($curl); 

With that, if you just use cURL from the command line: curl "https://example.com/rest/checksms/9502ec34-5348-4096-838a-e7ac0cce9d74" --cert ./client_smsgate-in.pem:123456789 -k

Domain https://example.com/ rezolvitsya network pings pass. Tell me what could be the problem?

UPDATE: At the same time, I noticed that this error occurs as the script is run for the first time, if after completion it is immediately launched again, it crashes: error: 14094410: SSL routines: SSL3_READ_BYTES: sslv3 alert handshake failure. php -v :
