It looks like the Auth Token in your code above is valid, I think that I’m getting “Invalid Token” when I type this in a browser because I’m hitting a different Blynk regional server:

When I pop your code onto a NodeMCU, with my own Wi-Fi credentials, I get this in the serial monitor when I reset the board:
