Vb.Net can upload a file to dropbox

Can you help me guys?
Im trying to upload my first file to dropbox using vb.net. But Still have error: Status-Code:0, Content-type:0
My code below, can you correct me where do I do a mistake?

 Public Sub Main()

        Dim sourceFile As String = "C:\Users\rw\Desktop\Proximus_logo.png"
        Dim data As Byte() = File.ReadAllBytes(sourceFile)
        Dim RestClient As RestClient = New RestClient("https://content.dropboxapi.com/2/files/upload")
        Dim request As IRestRequest = New RestRequest(Method.POST)


        request.AddHeader("Content-Type", "application/octet-stream")
        request.AddHeader("Authorization", "Bearer <token>")
        request.Parameters.Clear()
        Dim meta As String = "{\ path\:/home/proximus_logo.png \mode\: add \ strict_conflict\:false,\autorename\: true,\mute\: false}"


        request.AddHeader("Dropbox-API-Arg", meta)
        '  request.AddHeader("Content-Length", fileLength.ToString())

        '   request.AddParameter("path", "/home/proximus_logo.png")
        '   request.AddParameter("mode", "add")
        '   request.AddParameter("autorename", True)
        '   request.AddParameter("mute", False)
        '   request.AddParameter("strict_conflict", False)

        request.AddParameter("application/octet-stream", data, ParameterType.RequestBody)


        Dim response As RestResponse = RestClient.Execute(request)

        If response.IsSuccessful Then
            Console.WriteLine("SUCCESS: " & response.StatusDescription)
        Else
            Console.WriteLine("FAILED: " & response.StatusDescription)
        End If

        Console.WriteLine(response.Content)
    End Sub

Based on the output you shared, it looks like you're getting a status code of "0". That's not a real HTTP status code, however, so it looks like the HTTPS connection itself may not be succeeding. Is there any reason (e.g., proxy, firewall, security software, etc.) that you wouldn't be able to connect to https://content.dropboxapi.com?

You were right, Thank you.

I spend long hours solving this problem. It was a proxy problem.
