Is blynk-cloud broken? [SOLVED]

Hello, all my devices today could not connect to blynk-cloud.
I thouth something was with wi-fi connection.
I connected one of my device to computer and started debug.

i’ve checked on library versions 0.5.2 and 0.5.3 - result is the same -no connection.

what is wrong?

is it any resource to check blynk-cloud state ?

Perhaps your region is part of the 0.84% ?

Something very strange is happening.

I’ve used simple clean example for NodeMCU.

  1. not working source:
void setup()
{
  // Debug console
  Serial.begin(115200);
  Blynk.begin(auth, ssid, pass);
}

void loop()
{
  Blynk.run();
}

result:

  WiFi.begin(ssid, pass);

  Serial.print("Connecting");
  while (WiFi.status() != WL_CONNECTED)

    delay(500);
    Serial.print(".");

  Serial.println();

  Serial.print("Connected, IP address: ");
  Serial.println(WiFi.localIP());
 

  Blynk.config(auth, "blynk-cloud.com", 80);

Can somebody explain what has changed ?? and why the first variant suddenly became not working??

Any reason for the old Blynk library?

some of my devices are not easy reachable for upgrade firmware. okey i will continue research and post results here.

Hey I have noticed a difference in connecting between port 80 and 8080 on blynk-cloud, maybe try that on your testing?

Seems something was messed with my wifi router (but i didn’t make any changes in the config). I have reset it to default state and reconfigured wifi with the same credentials. And then everything worked as expected. I don’t know what was the reason.
