HTTPS Certificate binding error:A specified logon session does not exist. It may already have been terminated.(Exception from HRESULT: 0x80070520)

On IIS 7.0, we were trying to bind a wild card certificate to one of the externally available SharePoint sites over HTTS and we get the following error.

I have gone through many blogs online suggesting various options. This is what worked for us.
We reexported the certificate with extended properties box checked, deleted and reimported current SSL certificate on IIS, removed all the existing binding settings on the destination server and rebinded.
