After Fedora 43 upgrade, cluster shell not working

I have alias and have clustershell set up to acces all my hosts. It is not working after Fedora43 upgrade. when I run my alias get following message:

Can’t connect to display `unix:0’: Permission denied at /usr/share/perl5/vendor_perl/X11/Protocol.pm line 2263.

More details please:

Thanks.

Looks like the software is looking for an X session. Fedora w/Gnome and KDE are Wayland powered

inxi shows that you are using gnome, and thus your session is not an X session (as
Flo said).

Can you double check by executing: xrandr -q ?

It should work if you are in an X session.

I’m confused here, but I don’t know well wayland (to say the least) nor Gnome.

Tell us precisely what is your “alias” ?

Also, do you set the DISPLAY variable ?

PS: Again, when you paste, use the </> button (Preformatted text): the seventth from
the left in the top bar of Reply form.

I created a new local account and Clustershell is working with the account.

Good.

You can then compare the various profile files of those 2 accounts (if you are in mood
to dig further).
Assuming their shell is bash, start by comparing the .bashrc and .bash_profile
