Antonio, perhaps I can help.
Is your Moxie on a subscription?
Are you located in the US?
I find if Moxie has a low battery it won’t connect to Wifi. Plug into power and charge overnight. Then try connecting to Wifi.
Sometimes I find Moxie takes a while to connect to Wifi, I have to turn my Wifi router off and then on a few times but that could be because I use a very cheap pocket Wifi known to be unreliable.
