I have a problem with function:
I have local server on Raspberry Pi. Works good.
With example below, works.
Blynk.begin (auth, ssid, pass, IPAddress(*local IP*), 8080);
but with public IP not works.
Blynk.begin (auth, ssid, pass, IPAddress(*public IP*), 8080);
It’s not problem with port forwarding because in webbrowser I can see admin panel. Even I can log in via app on smartphone. Addres server in app can be private IP, public IP, even with no-ip domain (via http port and https port).
Blynk.begin in arduino code works only on local IP. Why?
