WHMCS/Prve debug connection issue

[slrslr]

Hello,

when i add new Prve server in WHMCS 6.3.2 / Products / Servers, save and test connection it says "FAILED:".

How can i please debug the reason why it fails? My WHMCS is hosted on cPanel + Apache server. In PVE v. 5.0-23 /var/log/pveproxy/access.log i can not find any related access.

I added line error_reporting(E_ALL); into this module files and found this error line:

PHP Notice: Undefined variable: success in /home/myusername/public_html/modules/servers/prve/prve.php on line 234

in /admin/error_log file. Here is the /modules/servers/prve/prve.php on line 234 :

function prve_TestConnection(array $params) { try { // Call the service's connection test function. $serverip = $params["serverip"]; $serverusername = $params["serverusername"]; $serverpassword = $params["serverpassword"]; $proxmox=new PVE2_API($serverip, $serverusername, "pam", $serverpassword); if ($proxmox->login()) $success = true; $errorMsg = ''; } catch (Exception $e) { // Record the error in WHMCS's module log. logModuleCall( 'provisioningmodule', FUNCTION, $params, $e->getMessage(), $e->getTraceAsString() ); $success = false; $errorMsg = $e->getMessage(); } return array( 'success' => $success, 'error' => $errorMsg, ); }

230 line is: $success = false;

Please kindly let me know if You need further information? Thank you
