Basic Infos

I build an alarmclock with a 6-digit leddisplay with a TM1637 connected to my home system via MQTT.
I set the times and en/dis-able the alarms in NodeRed on my phone and send that via MQTT.
I am already sending every minute the current time from the ESP to NodeRed as a kind of keep-alive but
that doesn't help.
I have used this library on other projects with ESP8266's and then I had no problems.
I don't know if the problem is related to this library or not.
I'm using latest version of Arduino IDE

Hardware

WiFimanager Branch/Release: 2.0.3-alpha

Esp8266/Esp32: ESP32

Hardware: LILYGO TT7 v1.5 with ESP32-WROVER-B

Core Version:

Description

Connection is lost after 24 hours

I think the ESP loses contact with the WiFi and does not reconnect.
