Unable to connect to Hotspot

Hi, I am working on a project that uses blynk and Arduino Nano 33 IoT. When I connect it via Wifi at home, it works and functions properly. However, when I connect it via my phone’s Hotspot, Blynk shows that it is offline and will not connect. What is causing this?

What does your serial monitor show?

It could be that your phone is creating a 5GHz hotspot and your device requires 2.4GZHz, or that your phone’s hotspot function or your mobile ISP is blocking either the port being used by your device or blocking the Blynk data packets.

Pete.
