Help with standalone doser

[gatekeeperdi]

Hi there,
I have got a standalone doser 2.1 that I have been controlling with the GHL connect app on my Samsung S8 phone. I tried to connect to it today, using the hotspot that it has worked with but it will not connect. I have then tried to connect it to the GHL control centre on my laptop, using windows 10. It let me connect with the USB and change the dosing settings that I wanted to make. Now the GHL logo is flashing blue to yellow. Please can someone tell me what it means and how to fix it?

The logo light can flash two colors simultaneously.
Blue: Connected
Yellow: One or more dosing container fluid levels are running low.
