no connection?!

Hello!

Unfortunately I still have no connection?!
I have installed version 1.749 and have looked through the manual several times for a clue.
Unfortunately I get no connection… What am I doing wrong?

Here are my key points…:
Windows 10, Script 1.749, Ableton 11.1

My PC is in the mobile hotspot of my phone. I don’t have a router for the internet.
My touch monitor is a Hannspree.
Shouldn’t it work really well?!

Where could the problem be?

I really want to get the software running!!!

Thanks for the help!!
