Invalid token for shortcut

Solved
1

Hello everyone, I flashed the esp32 board using the template from the blink site, everything works, now I wanted to make a shortcut according to this instruction:

made a ping cloud.blynk.cc
And gave me ip 139.59.206.133
Later I copied my auth token, and tried the get request

139.59.206.133/aeaххххххххххххYS7Wn/update/V0?value=1

or

139.59.206.133/aeaххххххххххххYS7Wn/update/D19?value=1

And gives out all the time: “Invalid token.”

my Region: sgp1
Am I using the correct IP?

First of all, it’’s blynk.cloud

Secondly, you shouldn’t be hard-coding the IP address of the Blynk cloud servers for Blynk IoT, there is a much better solution which is to use the regional subdomain to identify the server, such as lon1.blynk.cloud for tge London server.

Thirdly, the API syntax has changed for Blynk IoT. The new syntax is documented here:
