Device Breathing Cyan But Cannot Connect!

I am working with 5 Photons with different projects.
two of them sending data to particle cloud as alarming system for power failure indicator (transmitter and receiver Photons)
others web hooked with Thingspeak.com for Temperature reading.

I am facing many times disconnected from console but the devices RGB breathing Cyan!
only one devices where working normally.

I tried to troubleshooting using blank loop(), but it showing same status.
I don’t know how I can trace the problem and from where I start.

@Lahmdi - mind following the instructions here and opening a support ticket (support.particle.io)?
