Connect to an esp32 from afar

This line returned an error
uci add_list zerotier.my_zt_net.join=<My_network_Id>

-ash: syntax error: "unexpected newline"

I did go through this

without the remove wan part and my router shows up in zerotier and I can get to it using the zerotier ip

but my esp32 that is connected to the wifi of the yellow box does not show up

I wonder if clients, it shows offline but it is actually working. It show on boot (esp32 boot) but the program running on it really does not generate much traffic

Thanks for looking
