I am getting the following error intermittently:
PHP Fatal error: Uncaught [6] Could not resolve host: pdfcrowd.com

What is causing this?

Hi,

This error message indicates a failure to resolve pdfcrowd.com to an IP address.

Possible causes may be a lack of network/internet connectivity, a DNS server misconfiguration, a firewall, or there is another restriction in your network.

I would recommend that you contact your network administrator or ISP to see if they're able to assist you with troubleshooting the problem.

what i find strange is i can access pdfcrowd.com website but the url to pdf api does not work???

API servers are on different machine than web site.

You can try some network diagnostic tools to see the route to our servers e.g.
$ mtr -rw pdfcrowd.com

If you are using new (Beta) API, try also:
$ mtr -rw api.pdfcrowd.com
