I try to send a SOAP-loginRequest to the POA and always get Status Code 59943.

Response:
<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<s:Header/>
<s:Body>
<loginResponse>
<status><code>59943</code></status>
</loginResponse>
</s:Body>
</s:Envelope>



Request:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Header>
</soap:Header>
<soap:Body>
<loginRequest>
<types:auth type="types:PlainText">
<types:username>kdokridjkslk</types:username>
<types:password>kdokridjkslk</types:password>
</types:auth>
<application>Time Connector</application>
</loginRequest>
</soap:Body>
</soap:Envelope>


When I send a getItemsRequest, it's the same problem.
My requests seems to be valid, because when they are invalid, I get other status codes.
The other error codes usually also come with a description, for example code 59905 has the description "Bad parameter passed to a NCSP function". But the code 59943, which I cannot find any info about, comes without a description.

Please, what does code 59943 mean?

Thank you!
