Plesk API: 502 Bad Gateway, Subscription

[Stuart1]

When ever I create a new subscription the page returns:
502 Bad Gateway

I found this article but it did not resolve the issue. http://kb.odin.com/en/118671

This error only occurs when I create a new subscription.

I use the following XML:

<webspace>
    <add>
        <gen_setup>
            <owner-login>$user_name</owner-login>
            <name>$domain</name>
            <ip_address>$ipaddress</ip_address>
            <status>0</status>
        </gen_setup>
        <hosting>
            <vrt_hst>
                <property>
                    <name>ftp_login</name>
                    <value>$user_name</value>
                </property>
                <property>
                    <name>ftp_password</name>
                    <value>$password</value>
                </property>
                <ip_address>$ipaddress</ip_address>
            </vrt_hst>
        </hosting>
        <plan-name>$plan_name</plan-name>
    </add>
</webspace>

The user is successfully created, but I get the 502 error.

Can anyone please help me solve this issue, Thanks.

How? Where? After what?

I have a plain php file that has the CURL script that connects with the Plesk server to grab the customer information. I can retrieve info, add new customers, but when I add a customer to a subscription I get the 502 error.

I wish I could show you a log, but I don't know where I could look for them.

My api to connect to plesk server is an official plesk api

This is driving me nuts, why would I get an error when creating a new subscription but not when im adding a new domain?

Proxy log:

2014/12/04 13:27:20 [error] 7658#0: *3 upstream prematurely closed connection while reading response header from upstream,
client: xxx.xxx.xxx.xxx, server: domain.com,
request: "GET /page.php HTTP/1.1",
upstream: "https://xxx.xxx.xxx.xxx:7081/page.php",
host: "domain.com"

I ran
/usr/local/psa/bootstrapper/pp12.0.18-bootstrapper/bootstrapper.sh repair
and there was an error described in the following article http://kb.odin.com/en/120426 but after doing this I still get 502 error.

Instead of getting the XML response I get the 502 Error.

Problem Resolved the issue was the Plesk Application Firewall or Watch Dog. Unfortunately I removed Watch Dog and disabled the firewall at the same time in my desperation so im not sure which fixed it but it resolved the 502 error.
