If using self-signed SSL certificate the Membership Request will fail with an Unknown Error.

I've just been looking in to a problem where the membership request is failing on a site where I have a temporary self-signed SSL cert on the server.

The Webpart errors and displays Unknown Error.

In the logs you will find.

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

I have had this problem before with some other projects and I assume the issues is down to the code is failing as it trys to load the email templates using a web address, rather than directly from the feature directory. When it finds an erorr with the SSL cert it through an exception.

There is a way (not that I can remember off the top of my head) that you can tell .Net to ignore SSL errors.

Once I get my real cert installed, I'll confirm that this was the problem.

I believe this can be solved by registering the certificate with SharePoint. See this discussion thread:

I installed a proper SSL cert and it did not work until I registered the root CA certificate with SharePoint.

Thanks for the pointer!
