ESP32 restarts after exakt 60 seconds - Core 0 panic´ed

Issues
1

Hi

I have a problem with my ESP32 controller with WLED.

WLED ran stable for the last 2 years without any problems. Since yesterday the controller started to restart after exactly 60 seconds.

As far as I know nothing has changed in the network.

What have I already tried?

  • Controller without LED’s operated (so only the controller without consumers)
  • flashed a 2nd ESP32 with the latest WLED version (Webflasher)

also the 2nd ESP shows the same behavior → after exactly 60 seconds it restarts.

If I take out the hooks from the times within the Time&Macro settings and save, they are there again after the reboot.

I get today a 3rd completely new ESP32 delivered and would test it again with the wled (fresh install).

Do you have an idea?

Attached are the logs that I have saved via the Webflasher console.

Do you have HA integration?

3

Hey :slight_smile:
First of all, thank you for the fast reply :slight_smile:

If you mean Home Asistant → no i dont have HA.

My network ist a fritzbox with Unifi AP if this helps.

4

Get a debug build and monitor serial output.
You may also want to fire-up Wireshark to see what’s happening on the network.

5

do you have a link how to get a debug build to monitor serial output (or some tutorial)?

You mean its network related?

6

@srg74 used to have debug binaries in his Github repo.

I am just suggesting things to check to isolate the cause. WLED does not reset on its own.

7

Thank you for the info!!!
Will try it.

Its confusing that its exactly after 60 seconds (it reboots after 60 seconds uptime)

8

so i flashed this binary

with the ESP-Flasher

If the controller is NOT connected with the WIFI (default WLED AP with ip 4.3.2.1) the controller is stable.

If i connect the controller with the Wifi ( i tryed different SSID´s and with simple passwords) the controller restarts every 60 seconds.

flashed now the b4.

this is the log from the console:

So after a long search I seem to have discovered the problem.

The fritzbox firmware versions from 7.50 make problems in some constellations and lead to reboots. A downgrade to 7.29 (not save, old firmware!!!) Lets the esp run stable again. The wifi I distribute via unifi AP’s. Hope this helps some
