QR code does not connect to wi-fi

I have made a project in studio and I published it but when I scan my WEBAR QR code it tells me unable to connect and my wi-fi on my android is connected can you help

I just added my own topic without knowing you have already had same issues.
I was trying figure out what is going on and I went to my project page at ZapWorks, the project was gone.
So re-created the project, replace the QR code and all that. Then I tried to published it but I got same not connected error. The issue is getter worse and worse…
