Blynk app "Can't connect to host" Issue

Hi,
I have a problem with Blynk App. I run local server on RPI Zero W. Everything looks ok, I have access to server via web browser on RPI, PC and iPhone. Although I cant connect app to my server. I enter my login, password, set server to custom and set ip address to 192.168.0.33 port 9443 which is my RPI address. App keeps saying “Cant connect to host”. Can anybody help me? I tried different accounts. 192.168.0.33 : 9443 is correct IP address.

SOLVED

Turned on “local network” on app settings in ios settings.
