Please edit your post, and add triple backticks ``` before and after your whole sketch.

Should be at the top of your sketch. The first lines.

What Blynk library version are you using?
It will tell you this in the serial monitor at the bottom of the Blynk logo.

Pete.

Are you sure that the authentication token in your sketch matches the one in the device information tab ?
Have you tried a different one ?
