Describe the bug
I have a https://github.com/nlimper/Mini-AP-v3 and usually it works fine. However, a few days ago I noticed my tags didn't get updated any more in the morning (around 08:00 and 09:00, long after the "no updates between" period has ended, see below). When I checked the AP, the screen was black and only the blue led was on. First i simply unplugged the AP and plugged it back in, but that didn't solve the problem. I tried resetting the ESP32 S3 and (later) the ESP32 C6 but initially without succes. The most success I've got so far is shorting the IO0 pin of the S3 to ground and then plug back in the power. This doesn't work every time, and perhaps it's another combination I do that wakes up the AP, but I'm not sure about that.
I've checked all solderjoints once more and I'm pretty sure all are okay.

This is the firmware version I use:
env: ESP32_S3_16_8_YELLOW_AP
build date: 2023-10-08 15:55
esp32 version: 2.01b
filesystem version: 2.01b
psram size: 8357783
flash size: 16777216

The C6 is on the latest FW version.

The access point config is as followed:
IEEE 802.15.4 channel: auto
LED brightness: 10%
TFT Brightness: 10%
Language: English
Maximum sleep: 10 minutes
No updates between: 23:00 and 06:00
Preview images: yes
Wifi power: 8.5 dBm
Time zone: CET

Is there a way to obtain log files or get a better understanding of what goes wrong? (And do an even better bug report, if that's necessary?)
