Why my live streaming control panel is not opened?

I’m trying to do 360 live streaming on youtube.
at first I can get in to live streaming control panel while I connect my Z1 to my phone(galazy note 10+).
But after that I try to reopen it with my Z1’s IP address, it’s not working.
I can’t open it so I can’t put my new stream key.
Can you help me?
