External storage 2nd HDD error

Hello,

I have installed Next Cloud 14 on my computer. I have it up and running. I have setup a local external data location on the computer and connected it to the main server. See the first picture below. As it is connected and green I then go to my user account and confirm that it is linked. Please see the second picture. At this time it shows that I am not able to use it. I have gone into Ubuntu and opened access to 0770. It is still not working. What am I doing wrong? Would you please help.
