My first try to config hyperion ng ending with that error:
I try to found that error over Google, but I can't found anything with "signal=FPE".
I also try to uninstall hyperion ng with "sudo apt remove hyperion" and reinstall it, but without any result. And yes, I also reboot the pi.
Before I got that "crash" I was in the setup of the LED's. Sadly I only got a signal on my right side and I try several things. In the last step I decide to make a reset andset all LEDs to 0 and safe it. After that the Web Interface was crashed and I got that error.
