Hello, normally everything works perfectly. But I recognized twice that the ESP8266 crashes if the NTP server is not reachable. There where several connection attempts - then after few minutes a crash. As mentioned this does not happen always - just few times.
Please find the last serial output plus stack trace below.
The crash itself is not really critical; as long as the ESP8266 will restart automatically.
Thanks, JC
