At least concerning nntp this sounds like bug#52735 (which I continue to
experience); see also the thread beginning at
<https://lists.gnu.org/archive/html/info-gnus-english/2023-06/msg00014.html>.

I use the following hack, added to my ~/.emacs.d/.gnus.el file:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(defun srb-gnus-group-get-new-news (&optional arg one-level)
  (interactive "P")
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-group-get-new-news))
    (gnus-group-get-new-news arg one-level)))

(defun srb-gnus-summary-next-unread-article ()
  (interactive)
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-summary-next-unread-article))
    (gnus-summary-next-unread-article)))

(defun srb-gnus-summary-next-page (&optional lines circular stop)
  (interactive "P")
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-summary-next-page))
    (gnus-summary-next-page lines circular stop)))

(defun srb-gnus-summary-scroll-up (lines)
  (interactive "P")
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-summary-scroll-up lines))
    (gnus-summary-scroll-up lines)))

(define-key gnus-group-mode-map "g" 'srb-gnus-group-get-new-news)
(define-key gnus-summary-mode-map "n" 'srb-gnus-summary-next-unread-article)
(define-key gnus-summary-mode-map " " 'srb-gnus-summary-next-page)
(define-key gnus-summary-mode-map "\r" 'gnus-summary-scroll-up)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

But this is brittle and doesn't always work.  If you find a real
solution, I'd be interested to see it.
