samba - Aug 2025 - could not connect to, Unable to find suitable address

Hello,

I have two samba server in my LAN but can only access shares from the domain
master, fileserver but
not from the other, athlux.
I already disabled the iptables firewall.

 * If I'm on athlux, I can mount shares from both, from athlux as well as
from fileserver

 * If I'm on fileserver, I can mount shares from fileserver but not from
athlux:
   mount -t cifs -o username=meyer //athlux/Backup4U /disk
   Password for meyer@//athlux/Backup4U:
   mount error(113): could not connect to 192.168.0.70Unable to find suitable
address.
   


Is there something wrong with my configuration?

The working samba server (fileserver) have the [global] section in
/etc/samba/smb.conf:
[global]
hide unreadable = yes
domain master = yes
wins proxy = No
hosts allow = 192.168.0.0/255.255.255.0
unix password sync = yes
socket options = TCP_NODELAY
encrypt passwords = true
hide special files = yes
os level = 64
oplocks = yes
username map = /etc/samba/user.map
log file = /var/log/samba/log.%m
map to guest = Bad User
max log size = 1000
passwd program = /usr/bin/passwd %u
logon home = \\%N\%U\profile
domain logons = Yes
preferred master = no
server string = Samba Server %v
workgroup = PrivateLAN
logon script = logon.bat
netbios name = FileServer

The not working samba server (athlux) have the [global] section in
/etc/samba/smb.conf:
[global]
unix password sync = yes
passdb backend = tdbsam
server string = %h server
workgroup = PrivateLAN
server role = standalone server
obey pam restrictions = yes
preferred master = no
encrypt passwords = yes
hosts allow = ALL
panic action = /usr/share/samba/panic-action %d
passwd program = /usr/bin/passwd %u
log file = /var/log/samba/log.%m
max log size = 1000
os level = 20
netbios name = AthLux
pam password change = yes
syslog = 0
dns proxy = no
username map = /etc/samba/user.map

Thanks in advance

The first one appears to be for a PDC and the second is for a
standalone server, but you haven't said what Samba version(s) and OS(s)
you are running, so at the moment it is a bit hard to comment further.

I'm using Samba version 4.13.13-Debian on both
