Project stays offline on ALL mobile devices

[DesertDrummer]

I’m a noob to Blynk. I created several small projects just to get familiar. The first, and simplest was working all the way up to last night. Now it shows as offline on all of my mobile devices. I’ve tried resetting the hardware (ESP8266), rebuilding the code, logging out/then in to the mobile Blynk app to no avail.

I have not changed the code since it was working. I confirmed my local WiFi connection from the ESP board is working fine. I turned on BLYNK_DEBUG but can’t tell if I’m successfully connecting to the Blynk server. I can ping blynk-cloud.com and telnet to blynk-cloud.com:8442. My other two sample projects are online on all of my mobile devices, although they frequently go offline momentarily.

I read the troubleshooting doc at http://docs.blynk.cc/#troubleshooting but nothing there seems to apply to my situation.

Here’s the output from the serial monitor:

Here’s the code:

    // Go to the Project Settings (nut icon).

      } else {

      }
    }

      value = param.asInt();
      Serial.print("value=");  Serial.println(value);
    }

    //-------------------
    void setup()
    {
      pinMode(LED_PIN, OUTPUT);
      digitalWrite(LED_PIN, HIGH);
      
      // Debug console
      Serial.begin(115200);
      Serial.println("Entering Setup...");

      setupWifi();

      // Blynk.begin(auth, ssid, pass);  // no need for ssid, pass since Wifi already established.
      Blynk.config(auth);
      
      timer.setInterval(1000L, blinkLedWidget);
    }


    void loop()
    {
      
      Blynk.run();
      timer.run();

      // gradually illuminate a Blynk LED
      i = i + 4;
      if (i > 255) {
        i = 0;
      }
      led2.setValue(i);
    }

Any ideas why I suddenly cannot get this project back online on my serial monitor. Thanks!
