Can't connect QNAP or Win10 box to Unraid server via SMB

I'm fairly new to Unraid, and was in the process of copying over my media from my QNAP NAS last night when all of the sudden, I got a bunch of errors on the QNAP telling me it had failed to copy over the media. I had already copied something like 6TB, so I'm a little confused as to why it dropped. So I tried to remove the connection in my QNAP NAS, and re-add it, only to be given this error message: I also tried to go to my Windows 10 network, and it doesn't show.

I found and fixed the unRAID SMBv1 access issue via this article: https://www.techcrumble.net/2018/03/you-cant-access-this-shared-folder-because-your-organizations-security-policies-block-unauthenticated-guest-access/ I had followed BobPhoenix's enable "SMB 1.0/CIFS File Sharing Support", also updated my hosts file per your earlier suggestion, the step in the linked article was the last step I needed. It's a Win 10 "rookie mistake" by me. (I'm new to Win 10.)
