Im using an ESP32 with local server.
After booting, the ESP32 connects to my wifi and connects to the local blynk server.
Everything works good and I sync the time every 15min.
But after about 60min the ESP32 looses connection to the blynk server and cant reconnect until I restart the ESP32 manually.
Connected to the Serial Monitor of the Arduino IDE gives me this:

Does anyone have an idea what I can do to locate the source of this problem?
