In general, when calling external service requests, sometimes due to configuration problems, PHP will report a PHP_ network_ Error in getaddresses: getaddrinfo failed: name or servicenot known:

reason:

PHP host cannot connect to DNS server

Analysis: for example, what is your access request www.leyangjuntestxxxx.com Our services

You can: Ping or   Telnet to see whether the domain can be accessed, whether there is a response

If you can’t Ping, your service is connected to a DNS server with problems

General solution:

1： You need to check whether the requested remote host is in/etc/hosts of the local machine

2： Need to check the rules of the firewall, is it blocked by the response

3： You can manually bind the host in the/etc/hosts file
