can't connect to samba share folder from ubuntu to windows

I want to create a share folder from my ubuntu server to all my devices that are on the local network, I've created a folder in this directory /home/my_user_name/Library. then I run chmod 777 Library to get access for all users, finally I've add to the smb.conf the following lines:

[Library]
    path = /home/my_user_folder/Library
    read only = no
    guest ok = yes
    guest only = yes

then I've run:

sudo service smbd restart

then I've tried to access from my windows machine, I can see the shared folder but when I'm clicking the folder I have a pop up message Link

how I can get it to work?

also I've tried to access from my phone and I don't have permission

Can you ping your server from your windows client?

Please run the following commands and paste the results-

ip -br a
sudo ufw status numbered

this is to verify if a) your local ip is correct b) your firewall is open to the samba ports windows is looking for

if the firewall is enabled, but Samba isn't on the list, try

sudo ufw allow Samba

This will open up the correct ports through your firewall. Verify by running

sudo ufw status numbered

This will list all the current rules. Then you can delete specific rules by entering the rule number. for example:

sudo ufw delete 1

Let me know if this works

Change your share definition to this:

[Library]
    path = /home/my_user_name/Library
    read only = no
    guest ok = yes
    force user = my_user_name

Change my_user_name to an actual user name.

Then restart smbd:

sudo service smbd restart

Don't have all the information necessary on how you are set up but it may be because you are using Ubuntu 22.04 or maybe your home directory is encrypted or ...
