My Cloud no longer accessible, no light showing on front of unit

As of yesterday My Cloud drive is no longer accessible on my home network.
I have tried restarting it (powering on and off) I have also tried pushing the reset button for 4-5 seconds.
There are two lights at the back of the unit beside the network/LAN input. One is solid orange the other flashes green.
When I reboot or reset the blue light at the front of the machine flashes but after 5 mins or so the front light turns off completely.
So the only lights showing are the solid orange the flashing green light beside the network cable on the back.
Please help, this is my backup drive for my life & business. EVERYTHING is on it!
Fingers crossed s/one can help me get it back up and running.
Thanks, Sue

Ok wait, I managed to login to my device via https://files.mycloud.com and my drive & files have reappeared. Thank GOD!
But can I please ask why the light at the front of my device is not working? I presume it should be blue?
Is this something I should worry about / should I have the device looked at or repaired

@suebest If your My Cloud is a 1st generation, the front LED turning blue will go out after a while. Mine has been out for over a year. It still works.

Use this link to find the User Manual for your generation of My Cloud. Look at LEDs.
