Why is my NodeMcu ESP8266 not connecting to Arduino IoT Cloud despite successful code uploads?

Hey guys @Middleware & OS I’m trying to connect my NodeMcu ESP8266 V3 Lua CH340 Wifi Dev. Board to the Arduino IoT Cloud platform, but I’m facing issues. Although the board is not listed in the devices section, I’ve tried uploading code to various similar boards (NodeMCU 0.9, NodeMCU 1.0, LOLIN(WEMOS) D1 R2 & mini) using the Arduino IDE. The code uploads successfully, but the devices remain offline in the Arduino IoT Cloud dashboard.

Here’s the output from the upload process:

[info] Sketch uses 422468 bytes (40%) of program storage space.
[info] Global variables use 36184 bytes (44%) of dynamic memory.

Despite successful uploads, I’m unable to connect to the devices in the Arduino IoT Cloud platform. Any assistance would be greatly appreciated in resolving this issue and getting my devices online.
