Random stall of the gateway

[RalfWein]

Hi zivillian, hi all,

Unfortunaltely my "close issue" was too early.
The stall hapened several times again. But I could fix it to the Wifi connection.
If the Wifi disconnects for any reason, the ESP32 does not reconnect.
There are several discussions that this applies preferably on connections to a Fritz!Box. In my case it is a FB!
Solutions range from "cyclic reconnect" "to reboot after connection gets lost".

Hi, saw same issue. I saw the ESP32 disconnected from Wifi. Based on some research i replaced the original void loop() using below code.

void loop() {
  unsigned long currentMillis = millis();
  // if WiFi is down, try reconnecting every CHECK_WIFI_TIME seconds
  if ((WiFi.status() != WL_CONNECTED) && (currentMillis - previousMillis >=interval)) {
    Serial.print(millis());
    dbgln("Reconnecting to WiFi...");
    WiFi.disconnect();
    WiFi.reconnect();
    previousMillis = currentMillis;
  }  
}

Regards,
