Troubleshooting Domain Availability Problems

Domain results can sometimes be reported inaccurately. For example a domain showing available when it is already registered, or a domain showing as registered when it is available. This page explains the common causes.

Navigate to Utilities > Logs > Activity Log

Look at the WHOIS Lookup Error log entries made at the time of checking for a domain. The explanation and solution for the common errors are explained below:

Extension not listed

WHMCS can check the availability of over 200 different domain extensions as standard by connecting to the relevant whois server for the domain in question.

It does this by looking through a list of common whois servers contained with in the resources/domains/dist.whois.json file., then looking for any custom whois servers specified in the user-modifiable /resources/domains/whois.json file.

However the domain being checked in this case is not amongst them. There are two ways to address this error:

  1. You can add extra whois server details by following these instructions: http://docs.whmcs.com/WHOIS_Servers
  2. Alternatively, select your domain registrar as a lookup provider (if supported by the module) instead.

Error: 110 - Connection Error

This error indicates that your firewall is blocking the whois port; 43. Please ensure port 43 is open.

It could also indicate your server is unable to connect to the specific whois server listed in the /resources/domains/dist.whois.json file - ensure your server is able to connect to the whois server on port 43 for the TLD listed in this file.

Error: 110 - Network is unreachable

This error indicates that your firewall is blocking the whois port; 43. Please ensure port 43 is open.

It could also indicate your server is unable to connect to the specific whois server listed in the /resources/domains/dist.whois.json file - ensure your server is able to connect to the whois server on port 43 for the TLD listed in this file.

Error: 0 - php_network_getaddresses: getaddrinfo failed: Name or service not known

This indicates that an entry does exist in the resources/domains/dist.whois.json file for the TLD in question, your server is unable to resolve it.

Double-check with the IANA database that you're connecting to the correct whois server. If you are, speak to your server admin to investigate why you server is unable to resolve it.
