Hi, I’m new here. I started a project and getting the often quoted Invalid Token Issue. As said, I read all the previous Solved answers and tried everything as far as I can understand. Still mine says Invalid auth token. I hope someone can point out what I’m doing wrong. Code compiles and runs without issue. But the serial monitor is always showing invalid auth token.
My Hardware mode is ESP8266. Communication type - Sim800L (I think that’s what you are asking here).
Smartphone Version Android 10. Sony Xperia XZ3
Blynk server
Library Version Tried 1.1 and 0.6.1.
