I have a Comet (GL-RM1).
I cannot fully confirm but what I believe happened (because of the exact timing) is that we had a mild thunderstorm which killed a few of my electronics, specifically devices related to my router.
My Comet, my NAS, and my personal desktop were effected.
Initially, my Comet stopped working entirely.
Then it automatically started flashing the white light. I let it do that for a while (few hours) in case it was rebooting or something but nothing happened...
So then I tried to reset it by holding the button and it flashed blue.... But then it totally shut off after that. I couldn't do anything to turn it back on. So it was essentially bricked.
Finally, it came back up again (I have no idea how or why) but it still doesn't work... It just flashes white as though it needs ethernet but I have used four different ethernet ports which I confirmed work on other devices and it still doesn't work.
Essentially I think this brand new KVM is bricked... I've restarted everything connected to it and I have tried connecting manually and nothing works.
Any ideas? It sucks because I really liked this device.
