Drobo disconnects on its own and now won't mount

Hi.
Im on a mac os 12.4 monterey.Using Drobo 5d3.Over the last coupple of months The drobo unmounted on its own where the mac gave me a drives not ejected propperly message.
Last night the drobo drives where unmounted again and after restarting evereything the drives are not mounting.
I tried different ports,Cables and computers and no luck there.
The drobo startup shows a green light on the bottom left first followed by blue led then all green leds on the right are solid green.then 8 blue bottom lights turn blue.then all turns off and the left bottom led turns amber and nothing mounts.
Could it be a bad power supply?
Thanks
