IR not working on RLC 823a with last firmware

[user_587474691784750_587474691784750]

Hi, I'd like to rase a question to the community regarding IR stop working suddenly, without particular reason.
2 weeks ago I flashed the last firmware (v3.1.0.956_22041511_v1.0.0.30), and it IR was working fine until yesterday night without particular reason.
The night mode did not trigger at all (beside this I did not see the red light on the camera). I tried to active /deactivate auto night mode, but impossible to have it working. This morning, again I tried to hide the night sensor, but it was still locked. Thus I performed a Hard reset on my POE camera (with power on), and now it seems I can trigger again the nigh mode with IR light ON. Unfortunately the Firmware did not reset to factory (probably because I push the reset button with POE connected), but at least it is working now.
Does anybody already saw this behavior?
