Specified logon session does not exist

[Meatsauce]

I have a Buffalo NAS LS-XL5A9 and I am unable to map or browse to it on one of my Windows 10 systems.
The other system connects to it just fine.
When I try to map to it or browse the drive, i get an error message saying that \\LS-XL5A9 is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
A specified session does not exist. It may already have been terminated.
The drive is connected to my Router/Modem, which all my other devices are connected to as well.

Can someone assist?

Can you access it using the NAS Navigator?

The NAS navigator can definitely see it, but when i hit browse or map share, i get the previous error, and when i hit map share it tells me to create a folder named Share before i can do that

Windows updated overnight. Issues have disappeared. Very odd.
