Access share over wifi only "A specified logon session does not exist"

As of a couple days ago I can no longer access my Buffalo NAS share. I have't had any connectivity issues before. The odd thing is if I use a wired connection I have no problems access the share, but over wifi I get this error:

\\Your-Drive 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 logon session does not exist. It may already have been terminated.

I've read some other posts related to this error, and I've tried adding Windows Credentials from the post here and I've seen posts about using gpedit.msc but I'm using Windows 10 Home which doesn't have that (and I don't want to install a 3rd party tool). I've restarted everything (computer, router, modem, NAS) too.

Any other suggestions or ideas why it only fails over wifi?

Thanks

I got it working. I first disabled IPv6 and restarted but that didn't do it. Then I mapped another drive to the share but chose "connect using different credentials" and entered the same username\password that I used to logon to the laptop
