Moto360 does not connect to Home-Assitant

On my new Moto360 smart watch with Wear OS I installed the Home Assistant (Beta) and configured it from my Smartphone (Fairphone FP2 with Android 9 and Home Assistant (Beta) ), but when the Watch app starts it just shows
Instance
[local ip adress of my HA server]
Andere (Others)
[enter address]

When I tap on the local adress it shows “Connecting …” for some seconds and then
“Could not connect”

My smartphone and my tablet work fine with HA, as well as the PC with browser.
My local user account is the same at the watch and the smartphone.

How can I manage to connect the watch to the HA server ?

some users have difficulty connecting over BT, try to turn off BT and connect
