emacs-elfeed-org, bug #43243

I'm considering dismissing elfeed-org, it's useful but not unavoidable :-)

on machine B

Sorry I don't understand the steps you are trying to reproduce: in the
use case above I'm starting "emacsclient -c" from machine B when
remotely connected via ssh (-Y) to machine A; I'm running emacsclient -c
over ssh

"emacsclient -t" (over ssh) always works for me also, no crashes after
disconnection (no X toolkit used in this case)

I never tested using "Force pseudo-terminal" (-t) when connecting over
ssh: I should try that!

I usually use X forwarding over VPN over 4G connection: it's a little
bit slow but usable.

Ouch: it never happens to me, I mean /ssh:.../ TRAMP method always works
like a charm.  Have you tried installing "emacs-tramp" package?  I had
some issue with the built-in emacs TRAMP and realized that emacs-tramp
guix package is more up to date with upstream.

Technically is closed but actually it should be "exausted" :-D
