Desktop / mobile

I use a NodeMCU V3
From my computer I created 2 buttons that works well.
I created 3 slider to drive a RGB led.
It works from my computer but not from my mobile (android) or my tablet(android) : can not connect to remote device.

Thank you,

PS: Sorry for my english, I’m french

@buquet sorry for the delay. Do the devices show up on your phone, just offline, or do the devices not show up at all on your phone?
