Current firmware version v1.05.02
Current firmware date 18 Jan 2016
Hardware Version A1
Model Name DCS-5615
HOWEVER looking at the box it says A2 1.05
I'm in the US. I downgraded to 1.04 just to see if anything worked (it did not) and then i put the 1.05.02 back but the camera says "unknown" for the hardware version now

I tried IE, Chrome, FF. After you select the certificate file and press upload, it goes back to displaying the csr and "invalid public key" is shown for the certificate status.
