Trouble accessing Blynk project from mobile network

I tried to share my project QR code with a friend of mine. He is able to connect to my project when he connects to my home wifi, but when he connects to his mobile network he sees error “Project is not available… contact author”. I am using Arduino Uno board connected to my laptop and home wifi. Can anyone help me please?


Weird, if you are using the cloud-server I’d expect this to work properly. It shouldn’t make a difference where you connect from.

Maybe it has to do with the serial script. Are you able to connect the Arduino directly to the network in stead of via a laptop? Maybe with an ethernet or wifi card?

Mobile providers use different routing so you probably need the geo-dns fix.

@Santhosh hi. quick fix would be to put IP of server and generate token again.
