your token it should be ok, the message didn’t says that invalid token, it says “Requested pin doesn’t exist in the app.” .
what causes the problem, could be:
you didn’t accessed your project for a long time, and the pin archive was deleted (expired) on the server, and thus the “Requested pin doesn’t exist in the app.” message.
or, you never used the respective pin in the project, and it has not been initialized
workaround:
try to (re)initialize the values of the virtual pins from app or from hw side.
from app: add a slider for the respective virtual pin, start the project and slide it a bit, to push the values to the server. than you can delete the widget, and you should see the values in the api.
from hw, i use this method:
BLYNK_CONNECTED()
{
Blynk.virtualWrite(V_GET_UPDATE, 0); // init virtual pin on the server side
}
i use this virtual pin, for init http firmware update on the esp, via api. because sometimes the respective virtual pin can be unused for a long time, it happened for me that i received the same message as you “Requested pin doesn’t exist in the app.” when i tried to init the update. to eliminate this problem, i always init the virtual pin at startup in hw. seems it worked for me so far.

Get connected with USB before you try sim800.
Did you change the USB script for the Macbook com port?
Forget local server until you have connected successfully to the cloud server.
