"Response payload timed out" after 100 sendings to RTDB

[Juliocab]

Hello, I have been looking into this problem but I cant find a solution anywhere. I have a program that is gonna send accel measures to the RTDB every 10ms (this frequency doesnt matter as the problem persist if I send data every 10ms,100ms or 1sec), after 100 nodes updates the 101th is not received by the database and that error message appear. Then after 2-3 secs, the program continues sending until is the 100th time again and the problem repeats.

if (aux < 300) {
      if (Firebase.ready() && !Firebase.isTokenExpired() && (millis() - sendDataPrevMillis > timerDelay || sendDataPrevMillis == 0)) {
        sendDataPrevMillis = millis();
        timestamp = getTime();
        Serial.print("time: ");
        Serial.println(timestamp);

        parentPath = databasePath + "/" + String(cont);
        cont++;
        json.set(velPath.c_str(), String(cont));
        json.set(timePath, String(timestamp));
        //Serial.println(fbdo.isKeepAlive());
        Serial.printf("Set json... %s\n", Firebase.RTDB.setJSON(&fbdo, parentPath.c_str(), &json) ? "ok" : fbdo.errorReason().c_str());
        aux++;
      }
    }

This is the code that I have on my loop, as I only testing it sends a counter that is increasing every time. And this is what I can see in the serial monitor.

Because of session closed by server or WiFiClient bug in ESP32, you have to call fbdo.stopWiFiClient(); for every 1 minute when you use it repeatedly.

Thanks for answering! I tried what you said but it is still happening, at the 101th time it has the same error "Response payload timed out". It still dont clear for me, why is every 100 times I send something, the 101th fails, it doesnt matter if between each send are 10ms or 500ms or 1 sec.

I explain it already.

I call fbdo.stopWiFiClient() every 30 seconds and now it is working perfectly, thanks for your help!
