You're using the builtin GNUTLS support. There have been a number of
fixes to it over the years, so it could be worth trying emacs-26. If
that's not possible, the alternative is to switch to using the
external gnutls-cli command instead. Something like

(defun gnutls-available-p ()
       nil)

before you load gnus should do the trick.
