My Arduino rp2040 connect don't connect to wifi. I checkt my SSID and password. I copy thann in connect my laptop scucesfully to the wifi. But with my Arduino rp2040 connect it only returns "WL_CONNECT_FAILED/4"

that's the code i try but i didn't work. Sorry for my bad english i hope you could understand my problem ;D
