just slip server between auth and ssid.
When the geo fixed is rolled out you can just change xxx.xxx.xxx.xxx to blynk-cloud.com
Seriell Monitor:
Connecting to 139.59.206.133
thats all.
App is telling: “Device is offline”
Screenshot of Serial Monitor and confirm ping is 139.59.206.133 for sketch and app.
SSID and pwd correct?
Still struggling, take a new token from app and enter in the sketch.

Have you tried a new token since you made all the changes?
no, but i did now.
Still the same
Auth Key = 18a5b6b352af4ddc915a4c2d1ec8d91d
What library version are you using?
What does the following show you?
telnet 139.59.206.133 8443
It should connect you for perhaps a minute or so before dropping the connection.
Paste your formatted sketch.
connection closed by remote host
directly
that’s the correct response because with telnet you don’t provide a token, just means routing to the Blynk server is not blocked on port 8443.
Formatted sketch?
standard at first:
-#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
-#include <ESP8266WiFi.h>
-#include <BlynkSimpleEsp8266.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = “18a5b6b352af4ddc915a4c2d1ec8d91d”;
char server[] = “139.59.206.133”;
// Your WiFi credentials.
// Set password to “” for open networks.
char ssid[] = “ssidname”;
char pass[] = “password”;
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, server, ssid, pass);
}
void loop()
{
Blynk.run();
Serial.println(“Hello”);
}
had to add a - to the includes because of formatting in this editor
Sketch formatting: [README] Welcome to Blynk Community!
change 9600 to 115200
Move Serial.println(“Hello”); to last line of setup() NOT loop().
noting changed
Does the following in a web browser show you your project details?
https://139.59.206.133/18a5b6b352af4ddc915a4c2d1ec8d91d/project
Invalid token.
It worked for me.
You have either the wrong ip or wrong token in your project. Check them again until you get the correct info from the url in a browser.

ok, reinstalled Blynk app on my android, create a new projekt.
ping blynk-cloud.com
reply 139.59.206.133
open:

upload new token and checked ip in my sketch, upload this and get the same result:
Connecting to 139.59.206.133
Correction, the server is the last parameter so it becomes:
Blynk.begin(auth, ssid, pwd, server);
Hi!
When I do this, I get “Invalid Token.”
Thanks!
