Unable to Map Network drive to my Desktop

Hi,

I have spent over a year with this problem that has persisted through upgrading to Windows 11.

I have a NAS (My Cloud Home) that I have been using to back up files which 'requires' a desktop app that is now being discontinued to use but I can enable local access and have done but am unable to access it from my desktop.

I started building my own NAS with TrueNas in hopes of solving my problem by moving to a more custom system. The problem persists.

It is not SMB 1.0 enabled or not. It is not an Update. It is not a PC reset nor a network reset. Its not some registry edit. I have been having so many problems and have tried so much. I have given up.

ALL OF THESE PROBLEMS ARE FOR MY DESKTOP. I can connect to both the NAS's from my Laptop without a problem. Without editing any settings.

The specific errors for my Cloud Home NAS is that I am unable to connect with a 'undiagnosed error' or when logging in with my credentials it tells me either my password or username is wrong EVERY TIME.

My TrueNas just won’t let me log in no matter the password or username. I entered it correctly typing it in on my laptop giving me access. Also typing it in Word and copying it over guaranteeing I typed it correctly. Yet it still says I have incorrectly typed it. EVERY TIME ONLY ON MY DESKTOP.

I tried Wifi vs Ethernet. Same thing. I tried different internet. Same thing.

I'm at a loss and broken. What the hell could be causing this?
