Blinking LED

[den]

My OneRNG has a blinking LED now as well. It starts normally then flashes regularly about every 4 seconds or so.

I had put a heatsink onto the lid to try and keep it cool. It was running very well for about a week with no problems at all, but now it seems to have failed :-(

I get this in my rngd logs:

I tried upgrading to the later version with ssl whitening to see if it made a difference:

If it indeed has failed, I would like to replace it and will cover any cost. I am happy to wait, against any new developments.
