Rgb Led Clock

Hey! Thanks for this article & code, really interesting.
I've set everything up and have managed to compile and flash to a node mcu, but i don't quite get the blynk side of thing. I have got an auth code, added it into the code - i can see the nodemcu talking out to the cloud, but it comes back with invalid auth code everytime, and the device never shows as online in the blynk app.
Any ideas what i might be missing? Im new to blynk, so still trying to get my head around that side of it.
Any advice would be greatly appreciated!
