 * Looks like it has something to do with DNS resolution or caching for the domain.
   When I ping your domain name I get errors about Name Servers are on the Same 
   Subnet and refresh and expire values are outside recommended ranges – and the
   TTL is too high.
 * Not sure how they affect the call but researching the issue says that this is
   a DNS resolution issue.
 * You could try switching your API request method to CURL in the plugin settings
   and see if that helps.
 * This is the first time I have seen this issues, so I am not sure where to begin
   to tell you to start troubleshooting – except maybe ask your Host Provider about
   the error.
 * Regards,
    Don

 * Are they possibly on the same hosting provider, i.e., GoDaddy or something?

 * @ijustmetme-
    change the api method to CURL in the settings and see if that helps.
   This error is generally caused when fopen is disabled on the host server.
