One of 5 network shares disallow new file/folder in root

I have 5 network shares mapped via fstab running at startup.
They all used to allow me to create a new file/folder in the root of each one. Now, one of them will no longer allow this, although I can create files/folders in a sub-folder off the root. This means I can also edit files in any subfolder off the root.

Is there a maximum number of files/folders at the top level of each share?

All shares act normally from Windows PCs.

All mapping is the same for the shares.
//server.local/Documents /home/rich/smbmount/Documents cifs username=[UID],password=[password],file_mode=0777,dir_mode=0777 0 0

//server.local/Dowloads /home/rich/smbmount/Dowloads cifs username=[UID],password=[password],file_mode=0777,dir_mode=0777 0 0

//server.local/Music /home/rich/smbmount/Music cifs username=[UID],password=[password],file_mode=0777,dir_mode=0777 0 0

Ubuntu 22.04 Folder Creation Issue

If you are unable to create new folders or files in shares on Ubuntu 22.04, it is likely due to permissions issues. Ensure that the user account you are using has the necessary permissions to write to the shared folder. You can check and modify permissions using the command line, such as with chmod or chown commands. Additionally, verify that the Samba configuration is correctly set up to allow access to the shared folder, including ensuring that the smb.conf file includes the appropriate settings for the share and that the Samba service is restarted after making changes.234+2

If the issue persists, consider checking if SELinux is active, as it might be enforcing additional security policies that could restrict file creation.3

For troubleshooting, you can also try creating a new folder using the command line to determine if the problem is related to permissions or the graphical interface.2

Are you using Samba? I have never created shares with Windows, only GNU/Linux and for that I use NFS, not sure if that would work with Windows.

None that I'm aware of. What exactly would be the "top level" in your examples?
