Hi! The code below was working until today (or perhaps yesterday?). Now, it throws an error at the line
Dim responseArray As Byte() = myWebClient.UploadValues(postURL, “POST”, myNameValueCollection2)
The error is:
System.Net.WebException: ‘The request was aborted: Could not create SSL/TLS secure channel.’
Can anyone help? Full code below:
Public Sub MemberfulLogin() ' This is actually the Patreon login
Dim myWebClient As New System.Net.WebClient()
Dim myNameValueCollection As New NameValueCollection()
Dim myNameValueCollection2 As New NameValueCollection()
Dim postURL = "https://api.patreon.com/oauth2/token"
Dim client_id = ConfigurationManager.AppSettings("patreon_ClientId")
Dim client_secret = ConfigurationManager.AppSettings("patreon_ClientSecret")
Dim grant_type = "authorization_code"
Dim code = Request.QueryString("code")
myNameValueCollection.Add("code", code)
myNameValueCollection.Add("grant_type", grant_type)
myNameValueCollection.Add("client_id", client_id)
myNameValueCollection.Add("client_secret", client_secret)
Dim strHost = Request.Url.Host
Dim strProtocol As String
If strHost = "localhost" Or strHost = "online2.seterra.com" Or strHost = "onlinebeta.seterra.com" Then strProtocol = "http" Else strProtocol = "https"
myNameValueCollection.Add("redirect_uri", strProtocol & "://" & strHost & "/memberRedirect.aspx")
System.Net.ServicePointManager.Expect100Continue = True
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls11
Dim responseArray As Byte() = myWebClient.UploadValues(postURL, "POST", myNameValueCollection2)
Threading.Thread.Sleep(200)
Dim strResp = Encoding.ASCII.GetString(responseArray)
Dim objResp = Newtonsoft.Json.JsonConvert.DeserializeObject(Of MemResp)(strResp)
lblMessage3.Text = objResp.access_token
getMemberInfo(objResp.access_token, objResp.refresh_token)
End Sub
