To be sure we are on the same page, my desktop is the publisher, my
laptop is the client.
From my desktop:
--8<---------------cut here---------------start------------->8---
$ avahi-browse -a
+ enp7s0 IPv6 guix-publish-DESKTOP
_guix_publish._tcp local
+ enp7s0 IPv4 guix-publish-DESKTOP
_guix_publish._tcp local
+ lo IPv4 guix-publish-DESKTOP
_guix_publish._tcp local
+ enp7s0 IPv6 LAPTOP
_ssh._tcp local
+ enp7s0 IPv6 DESKTOP
_ssh._tcp local
+ enp7s0 IPv4 LAPTOP
_ssh._tcp local
+ enp7s0 IPv4 DESKTOP
_ssh._tcp local
+ lo IPv4 DESKTOP
_ssh._tcp local
+ enp7s0 IPv6 LAPTOP [2a:81:b6:9b:6b:88]
_workstation._tcp local
+ enp7s0 IPv6 DESKTOP [40:b0:76:0c:8d:47]

_sftp-ssh._tcp local

_sftp-ssh._tcp local
+ enp7s0 IPv4 DESKTOP
_sftp-ssh._tcp local
+ lo IPv4 DESKTOP
_sftp-ssh._tcp local
--8<---------------cut here---------------end--------------->8---
The output never changes, regardless of my laptop going to sleep or not.
You said "check if the publish server disappears" but why would it since it's
running on my desktop, which is not put to sleep?
Misunderstanding? Forgive my ignorance about Avahi! :)
Cheers!
