Local Blynk server on notebook on Windows 10 - wi-fi

I’v instaled local Blynk server on my laptop I can logging to it by webbrowser using 9443 port. My laptop is working in my network over wi-fi connection. My phone is running on the same wi-fi network and I can’t create a new account on my server. But when I connect my laptop directly to the switch via cable everything working fine. Where could be the problem? Any ideas?
