Invalid Auth Token on Blynk 2.0 New Servers

[MundoCampeones]

Hello, Very Important request , I have read all the solutions to this problem here and have applied the necessary changes like #define BLYNK_TEMPLATE_ID position , Blynk latest version 1.3.2 , but I still am having this issue. Here , I have provided the code please forgive my formatting if wrong. I have also put Serial Monitor Output. Please Pete or John reply to me as soon as you can.

@MundoCampeones

char auth[] = "XXXXXXXXXXX"; //Authentication code sent by Blynk

Remove this line of code and change this:

@MundoCampeones

Blynk.begin(auth, ssid, pass);

to this…

Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass);

If you’ve copied and pasted the three lines of firmware configuration from the Device Info tab in the web console and pasted it at the top of your sketch then it should work fine.

If it still doesn’t work then maybe you are experiencing a Geo DNS issue. In that case you should provide information about which country you are in, which regional server is shown in the bottom right of your web console, whether you are using a VPN, and how you are trying to connect (wired internet, GPRS etc).

Once you’ve solved the Invalid Auth Token message you need to read this, and edit your void loop so that it contains only two lines of code, and there are no delay() commands anywhere in your code…

Keep your void loop() clean

Pete.
