I have just gone through multiple threads, and as of MAY 2021, I am able to get into the HOMEASSISTANT network folder on WIN10 (OS Build 19042.985) by doing the following:
-enabling SMB 1.0 in optional features
-using the following configuration in HA/Samba (add your computer logon data, remove the +, make sure you have the apostrophe surrounding the password field):
workgroup: WORKGROUP
username: +your Windows logon user+
password: +‘your Windows logon password’+
allow_hosts:
- ‘*’
veto_files:- ._*
- .DS_Store
- Thumbs.db
- icon?
- .Trashes
compatibility_mode: false
It seems Windows is too stupid to prompt you with a logon window, and just blindly uses your Windows username and password. I found no way to actually fix this behavior, so you just have to set Samba in HA to use the same login info. Stupid…
