Cannot access folders with password (not public)

Hi to all.
I have two EX2 Ultra.
Same settings only different names.
The first is working perfectly.
The second which i just bought i have an issue.
I cannot access any folder if it is not public.
It keeps asking me the username and password.
I have one old one and is working fine.
I checked and all the setting are identical.
I tried everything.
If anyone can help i will be thankful.

ps. the program i use to transfer files is total commander.
