Yes, if the underlying code works.

I tested this but not thoroughly with self-signed certs (which it seems
you're using, though I can't be sure from your description).
This specific error could be due to many things; you need to either look
at the GnuTLS context yourself, post a recipe for duplicating the issue
here or in a bug, or ask in the gnutls-devel mailing list with that
recipe. Either way I will try to help you find the solution.
