When I had local UI installed I had to log in just like the very first time I setup HexOS. It took a little while. Just long enough to make me think I was doing something wrong but the dashboard came up
When I logged in I saw picture.
I clicked on the word local and saw this. I am guessing it's not exactly the word that is the trigger. That just happens to be where the mouse pointer was when I clicked.
I clicked on Switch to Hosted and went to the online dashboard so I started on local. Now to switch back I click the Return to Local button on the top banner.
If you don't start that way I am guessing the down arrow next to your server name will allow you to go back and forth.
