Provisioning Issues

This page provides information about general errors that may occur with multiple modules. For troubleshooting and debugging instructions, see Auto Setup Issues. For specific errors relating to individual modules, see the Troubleshooting section of the corresponding module's documentation page.

Hosting accounts aren't provisioned automatically

Watch the video tutorial for this feature.  

Review Configuration () > System Logs (Utilities > Logs > Activity Log in WHMCS 7.x and earlier) at the time of account creation for any error messages.

Server Command Error - Curl Error - Couldn't resolve host (6)

This error indicates that the account doesn't have an associated server.

Check for the following issues at the Servers tab while editing a product group at Configuration () > System Settings > Products/Services:

• • You have set the correct servers and that, if using a server group, Configuration () > System Settings > Servers lists at least one server for that server group.
  • The module is the same module that you selected in the Module Settings tab for the individual products.

Server Command Error - Curl Error - Couldn't connect to host (7)

This error indicates that a firewall on your server is blocking the connection. The port depends on the module in use:

• cPanel — 2086 and 2087
• Plesk — 8443
• DirectAdmin — 2222

Leave these ports open for inbound and outbound connections on the WHMCS server and the remote server. For assistance, contact your hosting provider or system administrator.

Other Module Command/Registrar Error

For steps to identify other module command or registrar command errors, see Troubleshooting Guide.

Required Product Module '' Missing

This error message indicates that a module command was performed for a product without an assigned module. Go to the Module Settings tab for a product at Configuration () > System Settings > Products/Services to check the module setting.

If the module selection has intentionally been left at None, consider using the Auto Release module. This module lets WHMCS open a support ticket or create a to-do list entry when a module command is performed to notify you that manual action is required.

Allowed memory size of xxxxx bytes exhausted

An error message like "Allowed memory size of xxxxx bytes exhausted (tried to allocate xxxx bytes)" indicates that WHMCS has reached the maximum amount of memory in the memory_limit setting in your server's PHP configuration. Adjust this setting until the error is resolved. For assistance, contact your hosting provider or system administrator.

Server Command Error - Curl Error - 28 connect() timed out

This error indicates that the attempted operation timed out. There are several common causes of this issue:

• The server is too busy dealing with other requests.
• The server required more than 150 seconds to provision the account.
• The server's site IP address does not match the server details in WHMCS.
• The server doesn't exist.

In order to resolve this, make certain that:

• Your firewalls aren't blocking requests from WHMCS.
• You have correctly configured SSL mode for the server at Configuration () > System Settings > Servers.

406 Not Acceptable

A 406 - Not Acceptable error usually is due to the server's mod_security rules blocking the query from WHMCS.

To resolve this, check the mod_security log for the triggered rule and that rule. If you do not have access to the server's mod_security log or to change the rule configuration, contact your server administrator or hosting provider.
