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?

Hey 🙂  
First of all, thank you for the fast reply 🙂

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

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

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

</div>

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

You mean its network related?

@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.

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

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

</div>

so i flashed this binary

> <https://github.com/srg74/WLED-wemos-shield/blob/master/resources/Firmware/%40blazoncek/latest/WLED_0.14.0-b3_esp32_debug.bin>

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.

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
