Need help setting up a private folder [More details inside]

Hello,

I have followed many different tutorials on setting up a private folder. Including this one from TechnoDadLife - https://youtu.be/SHGcFGSaLMs?t=243

When I try to log in to the folder I see the message in the image below.

Is anyone kind enough to help me with this problem? I need the help, support and guidance of the community. I have been trying to figure this out for the last 6 months on my own with no success

Any help and support would be greatly appreciated.

Update

I can access the share from Linux machine without a problem.

It seems the issue is with a Windows 10 machine.

If anyone has any suggestions on how to fix this, please leave a message below.
