StreamWriter gives Error 5337

Hello,

I am having a weird issue when implementing code (VB) behind one of my Infopath 2010 forms, that I use in Browser mode for SharePoint 2010. The form that I made takes purchase information such as Credit Card CID# and other things, and then sends that information using a post to our Authorizer. The form has been working fine until Production day and after making a few cosmetic changes such as color or font size. I re-published and I get a error upon submit(Onclick within my code). Now I have seen the error before, but I am sure you would be surprised when I said over night it fixed itself. Well this time around it didn't and so I started debugging and commenting out code to see when the form would spit the error. I found that it would right at this block of code below.

' post data is sent as a stream

Dim myWriter As StreamWriter = Nothing

myWriter =

New StreamWriter(objRequest.GetRequestStream())

myWriter.Write(post_string)

myWriter.Close()

Also here is the error that comes up in the Event Viewer:

Exception Message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

The remote certificate is invalid according to the validation procedure.

Any help to this would be appreciated.

Thank You,

Brandon

Update:

The exact line of code where the Error comes from is below:

myWriter =

New StreamWriter(objRequest.GetRequestStream())

And the objrequest comes from this block.

' Create HTTPWeb Request to Communicate with Authorize.Net

Dim objRequest As HttpWebRequest = CType(WebRequest.Create(post_url), HttpWebRequest)

objRequest.Method="POST"

objRequest.ContentLength = post_string.Length

objRequest.ContentType =

"application/x-www-form-urlencoded"

Thanks

Code
