problems joining wifi after days of successful operation

[hditter]

My esp32 s3 eye s2 board is disconnecting from the wifi network. After days of successful operation, all of a sudden, the board becomes unresponsive, and the green light is permanently blinking. The serial monitor says the following:

I have no clue what caused the error. I rebooted, unplugged, and plugged in again, but with no success.

Hi Miroslav, Thanks for reaching out. I have managed meanwhile to get it back to work. The ticket can be closed. Thanks anyway Best Regards Harald
