ok, update with a "bit" Progress but even more questions...
Instead of starting with the 1930 Switch I hooked up a AP22 to that orange led "timeout" switch and tried to create the site with that AP. Works instantly, AP was recognized, registerd it self online to the cloud and is now as a single device in my new Site named IFB. The switch where the AP is connected to is still "orange" even after doing a factory reset, same.
I did a connection test on the AP22 and it's fine:
So I doubt it is my fault somewhere but it looks to me either the Switch is dumb or the cloud have some issues...
And to add to this, if I connect my laptop to the switch or connect to the WIFI on that AP22 I'm perfectly online and just writing that post from.
