[SOLVED] Can not access using Proxmox PHP API

[kotakomputer]

This script below works fine on several server but only server from Hetzner doesn't.

<?php
require_once("pve2_api.class.php");

$pve2 = new PVE2_API("my-server-ip", "root", "pam", "my-password");

if ($pve2->login()) {
foreach ($pve2->get_node_list() as $node_name) {
print_r($pve2->get("/nodes/".$node_name."/status"));
}
} else {
print("Login to Proxmox Host failed.\n");
exit;
}
?>
​

To show detail error, I have added a break-point to determine the error point at pve2_api.class.php:

// Perform login request.
$prox_ch = curl_init();
curl_setopt($prox_ch, CURLOPT_URL, "https://{$this->hostname}:{$this->port}/api2/json/access/ticket");
curl_setopt($prox_ch, CURLOPT_POST, true);
curl_setopt($prox_ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($prox_ch, CURLOPT_POSTFIELDS, $login_postfields_string);
curl_setopt($prox_ch, CURLOPT_SSL_VERIFYPEER, $this->verify_ssl);


$login_ticket = curl_exec($prox_ch);
$login_request_info = curl_getinfo($prox_ch);

if (!$login_ticket) {
// SSL negotiation failed or connection timed out
$this->login_ticket_timestamp = null;
print '<pre>';
print_r($login_request_info);
print '</pre>';
print " SSL negotiation failed or connection timed out";
return false;
}

The above script will return "SSL negotiation failed or connection timed out" because the $login_ticket failed.

It's works when using https://my-server-ip:8006 to make sure the username and password is right.
Any suggestions how to fix this issue?

This script below works fine on several server but only server from Hetzner doesn't.

So it seems the problem is going out from Hetzner, not the PHP API wrapper or PVE?

Did you asked them if they have anything configured to block such login/access attempts?

Right, above code running well on other Data Centers, I have use it for hundreds servers.
Unfortunately, Hetzner does not help, I have open Ticket to Hezner but they told me to ask to forum.

i'd check wether a standard "Hetzner server" has the same ports listening on, then your "hundreds of working servers". Then verify that all those ports on your hetzner Server can actually be reached from the outside world.

That would tell you if hetzner does anything to block your requests.

I do reinstall, and just aware that Hetzner also provided Proxmox beside Debian. Use built in Proxmox image then Proxmox API PHP works fine.

So, the issue was caused by installing debian and then proxmox ontop ??

Right, on installation there are options to choose: Debian or Proxmox. Choose Proxmox instead.
