integrating WHMCS with Interworx - SOAP error

[gaspol]

I've just added my Interworx server's info + hash to WHMCS.

When I attempt to Accept an order and select Run Module Create, I get the following message:

Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://billing.abc.com:2443/nodeworx/soap?wsdl' : failed to load external entity "https://billing.abc.com:2443/nodeworx/soap?wsdl" in /var/www/html/includes/classes/WHMCS/Terminus.php on line 0

I can access https://billing.abc.com:2443/nodeworx/soap?wsdl from the server running WHMCS so I don't think it's a firewall.

What else could it be?

Thanks.

I see this issue has not been updated since 2014, and realize it, but it comes up pretty high in a search when looking for "WHMCS Interworx SOAP"

To resolve the issue with soap errors, make sure of the following:

• Your billing server firewall allows access on 2080 and 2443 (especially in cases on a remote billing server)
• Ensure SOAP is installed and running on the Billing Server.

If the above is set correctly, do the following when setting up the server:

• Leave the Hostname is completely blank.
• Ensure IP Address is filled.
• Ensure your server access username and password is used in the username and password fields. Do not use your administrative Nodeworx username and password. Make a new one in Nodeworx for this and use it instead.
• Create and copy the API Key from Nodeworx and Paste it in the Access Hash box on WHMCS (this is not needed, but nice to have).
• Select Secure and ensure the port is 2443. If not, override it and make it so.
