If you’re on linux and run `curl https://your-server`, do you get any errors about missing intermediate certificates?  If so, mono won’t be happy either.

There is likely an intermediate certificate in the chain that is not included in the bundle on the web server.  Comodo should have provided you with a set of certificate files, and you need to concatenate all of them together with the one for your server in the file first, then going through the chain all the way to the root being last in the file.  Then you need to point that the concatenated file as your nginx ssl_certificate.  The process is described here.
