Requirement to be connected to Wi-Fi

Does the Hue Essentials app require to be connected to Wi-Fi since recently?

In other words using it on mobile internet while connecting to a home VPN server is not possible anymore? I keep getting “Please check your Internet connection” message all the time since recently, before it worked fine over mobile connection with a home VPN server.
