WHMCS 6.3.2 does not supply server address into create API command

[postcd]

Hello,

I would like to ask for help. WHMCS 6.3.2 with module DirectAdmin which creates web hosting accounts on a remote server.

When invoice is marked Paid, the API command in Utilities / Logs/ModuleLog missing server IP:

Quote

://:/CMD_API_ACCOUNT_USER?action=create

but when i click Create button manually on that service page, in WHMCS then it works:

Quote

https://remote.server.hostname:2222/CMD_API_ACCOUNT_USER?action=create

Response for missing server is:

Quote

Array
(
    [error] => 1
    [details] => 3 -
)

I have even found decoded /modules/servers/directadminmodules/directadmin.php 

Website is using CloudFlare, pausing it, not made any difference

What are Your ideas why it does not supply it in case of automated setup and please what to try to fix it?
