samba guest access

I have a server with open tcp port 445. I used nmap with script smb-enum-shares and found this:

Starting Nmap 7.40 ( https://nmap.org ) at 2020-02-28 22:36 MSK
Nmap scan report for localhost (127.0.0.1)
Host is up (0.000052s latency).
PORT    STATE SERVICE     VERSION
445/tcp open  netbios-ssn Samba smbd 3.X - 4.X (workgroup: WORKGROUP)

It looks obvious, that i can access 127.0.0.1:445/IPC$ Anonymously I used:

root@kali:~# mount -t cifs //127.0.0.1/IPC$ /mnt/share/ --verbose -o "username=Anonymous,port=445"
Password for Anonymous@//127.0.0.1/IPC$:  
mount.cifs kernel mount options: ip=127.0.0.1,unc=\\127.0.0.1\IPC$,port=445,user=Anonymous,pass=********
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

I have also tried to log in via Nautilus, but still failed:

smb://127.0.0.1:445/IPC$

What am i doing wrong?
