WiFi network called CloudHub_xxxxxx

Hello, I hope you can help me with this, I'm trying to do this but I'm not sure what happened, I have a Raspberry Pi 4 Model B and installed the software ( cloudhub-pi4-factory-sdcard.zip ), So I connected raspberry with a mouse, monitor and it seems everything it's ok, on the monitor

12.056023 wlan0: link becomes ready
And I can see the devices connected on the raspberry, if I disconnect one device on the monitor i can see USB disconnect seems ok.

So I turned on WiFi on my laptop, started to scanning there are several Wifi connections but not the CloudHub_xxxxxx, I turn off wifi and turn on again..... several connections but not the CloudHub_xxxxxx.

I decide to looking for on my android's phone ... and surprise show me CloudHub_xxxxxx, I turn off the wifi on my phone and On again, started to scanning and show me CloudHub_xxxxxx, after that tried on my laptop again, but I don't know why is not scanning the CloudHub_xxxxxx .

I install again on the raspberry and the same result.

I tried with 3 laptop with the same result, no one of the laptop can scanning the CloudHub_xxxxxx, I tried wiht win10 64bit, win7 32 and 64 bit and the result is the same.

Waiting for your advice.

Thanks!
