Ah ha… well there is your issue! See, right there… where I am pointing…
Honestly, I can’t look over your shoulder… Post your complete sketch showing all connection info (blank out the auth, SSID and PASS).
What ESP hardware are you using?
How are you powering it?
Is your WiFi connection close and stable?
Have you tried any other examples?
Please… Work WITH me/us or you just might have to figure it out on your own.
