Why doesn't Samba public share work on Digital Ocean?

Question

Debian

Have samba on local Debian machine with config

[global]
workgroup = WORKGROUP
server string = Samba
security = user
map to guest = bad user
name resolve order = bcast, host
dns proxy = no
#=================== ========= Share Definitions =============================
[share]
path = /samba/allaccess
browsable=yes
writable=yes
guest ok=yes
read only=no

The problem is that everything is fine on the local network, the problem occurs when you try to raise the ball on DigitalOcean
netstat -ltun

Active Internet connections (only servers)

Windows sees smb, but says that it is not responding, with Linux the same reaction
What could be the problem?
