1 year ago The connection refused means that server does not respond to the request in time.
In your case the problem is internet access or network connection was interrupted.
When you manage to connect to network based on WiFi events, like this.
WiFi.onEvent(WiFiStationDisconnected, WiFiEvent_t::ARDUINO_EVENT_WIFI_STA_DISCONNECTED);
It's not necessary to use this in your code.
Firebase.reconnectWiFi(true);
The operation behind this library setting is to handle network reconnection for your device and it causes the reconnection conflicts.
Pathornnnnn
thai เริ่มต้นจากผมลองใช้ไลบรารี่นี้ กับ esp32 พอเริ่มทำก็ทำงานตามปกติแต่พอผ่านไป 1 นาที Serial port ค้างจากนั้นก็แสดง connection refused
eng (google translate) To begin with, I tried using this library with esp32. When I started doing it, it worked normally, but after 1 minute the Serial port froze and then showed connection refused.
thai เบื้องต้นผมศึกษามาเกี่ยว connection refused ถ้าเข้าใจไม่ผิดมันเกี่ยวกับการเชื่อมต่อ internet แต่ผมลองดูแล้วก็ไม่น่าใช่ หรืออาจเป็นเพราะผมใช้ firebasedata object เยอะไปรึเปล่า ฝากพี่ๆช่วยผมหรือแนะนำผมหน่อยครับ T_T
eng (google translate) Initially, I studied about connection refused. If I'm not mistaken, it's related to internet connection. But I tried it and it doesn't seem right. Or maybe it's because I use too many firebasedata objects? Please brothers help me. T_T
