Azure closing connection when trying to insert data using powershell

I am trying to insert data into a Azure SQLServer Table using a PowerShell4 script. The script is:

$cn = new-object System.Data.SqlClient.SqlConnection("Data Source=oayfco5zuq.database.windows.net;Initial Catalog=myDB;Integrated Security=False;User ID=myuser;Password=myUser;Encrypt=False;TrustServerCertificate=False");
$cn.Open()
$ds = new-object "System.Data.DataSet" "dsServers"
$ds.ReadXmlSchema('C:\SOAPR\LatestAdvice.xsd')
$ds.ReadXml("C:\SOAPR\LatestAdviceRes.txt")
$dtProd = $ds.Tables[0]
$bc = new-object ("System.Data.SqlClient.SqlBulkCopy") $cn
$bc.DestinationTableName = "dbo.LatestAdvice"
$bc.WriteToServer($dtProd)
$cn.Close()

XSD

<?xml version="1.0" standalone="yes"?>
<xs:schema id="LatestAdvice" xmlns="" xmlns:xs="http://ift.tt/tphNwY" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

    <xs:complexType>
      <xs:choice minOccurs="0" maxOccurs="unbounded">

              <xs:element name="id" type="xs:string" minOccurs="0" />
              <xs:element name="title" type="xs:string" minOccurs="0" />
              <xs:element name="category" type="xs:string" minOccurs="0" />

              <xs:element name="short_description" type="xs:string" minOccurs="0" />

            </xs:sequence>

        </xs:element>
      </xs:choice>
    </xs:complexType>

Data

<LatestAdvice>
  <row>
    <id>392062</id>
    <title>TITL</title>
    <category>Advice</category>
    <image>my-image-url</image>
    <short_description>Between the Honda CB Trigger and the Honda Unicorn, which one to buy?</short_description>
    <long_description>Lorem Ipsum
</long_description>
    <pubDate>Mon, 08 Dec 2014 17:47:00</pubDate>
  </row>
 </LatestAdvice>

Table Script

CREATE TABLE [dbo].[LatestAdvice]
(
    id VARCHAR(10) NOT NULL PRIMARY KEY,
    title VARCHAR(100),
    category VARCHAR(7),
    picture VARCHAR(500),
    short_description VARCHAR(60),
    long_description VARCHAR(5000),
    [pubDate] varchar(50)
    )

Host running the script is allowed in firewall scripts but I am getting

Exception calling "WriteToServer" with "1" argument(s): "A transport-level
error has occurred when receiving results from the server. (provider: TCP
Provider, error: 0 - An existing connection was forcibly closed by the remote
host.)"
At C:\SOAPR\LoadLatestAdviceData.ps1:10 char:1
+ $bc.WriteToServer($dtProd)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : SqlException

Any one any idea?
