Windows 11 posting invalid credentials

[JoshScotto]

Hello! I am new to TrueNAS Core and am having an issue with accessing my NAS via the Network tab in File Explorer on Windows 11. For a while it worked but once I returned from vacation the credentials no longer worked and I have no idea what changed in the 4 days I was away from my PC (remained untouched the entire time). I tried multiple sets of non-built-in users. No matter how many times I've restarted my PC or my NAS result stays the same. I created an SMB share of the storage pool as a whole. I tried changing my security settings, but that didn't work so I went back to "Send LM & NTLM responses" as the default. Any idea what I could do?
