Cant open web ui

I am trying to get started with Rhasspy but get stuck at the first hurdle.
I have got the add-on, installed it but when I select open web ui a new pane opens with “cant connect to server”

Anybody please. What am I doing wrong???

I had the same issue. I had to do a restore. Turned out I did not set the settings up for external mqqt. Such as server IP, user, pwrd. I left them blank. After restore, I filled in the required info and then never had any more problems opening the Rhasspy GUI. This of course only applies if you selected external mqqt as I did.

Thanks for the nod. It works!
