Webservice NF Paulistana does not return C#

Question

Dear friends, good afternoon. I have some problems with the use of the webservice of the São Paulo tax bill, where I need to get the Received Tax Notes and bring me this information. I already create the XML file to send in the function call, but it is not returning what I need, always returns something like "Server Internal Error". Apparently the file formatting is correct, but the message is not what it seems. Below the final result of my XML, check if it is correct.

To send carry out the POST, I use the HTTP schema, so I do not know if you need to change something there too.

Can someone please help me?

Thank you in advance.
