Couldn't connect blynk local server with app

Need Help With My Project
1

I have created blynk local server. In laptop. And have connected my phone with my mobile hotspot. But could not reach local server with my blink app why? But I can acess my admin portal from my lap chrome

2

Can you explain more about exactly what you mean by this? Are you connected to the same network as your laptop (using WiFi)?

What custom server settings have you used in the app?

Pete.

yes both device connected to the same network

So that answers my first question.

any more details needed sir

This indicates that your laptop isn’t getting an IP address via DHCP from your phone.

So, the devices are t going to be on the same network, and if you check you’ll see that the phone’s IP address will be in a totally different range to the laptop.

Maybe to do with the sequence that you’re starting the hotspot, connecting the laptop then starting the Blynk server?
