This is the code I am using to copy some data from a URL to text file:

 

 

Imports System.Net
Imports System.IO

Public Class Form1
  
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
  
Dim request As WebRequest = WebRequest.Create("https://01hw860645vm7/piwebapi/streams/P0RCrLRNEwjUSpQKLB67jLng60cAAAMDFIVzg2MDY0NVZNN1xBR0lfQ1VSUkVOVA/value")
  
Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
  
Dim datastream As Stream = response.GetResponseStream
  
Dim reader As New StreamReader(datastream)
  
Dim strdata As String = reader.ReadToEnd
  
Dim file As System.IO.StreamWriter
  file
= My.Computer.FileSystem.OpenTextFileWriter("C:\Users\1212832\Desktop\Test.txt", True)
  file
.WriteLine(strdata)
  file
.Close()
  TextBox1
.Text = strdata
  
End Sub
End Class

 

And I am getting the following error: "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."

I am totally new to this and facing small issues. Any help would be appreciated. Thanks in advance.
