NodeMCU not coonecting to blynk servers

My NodeMCU 1.0 seems like it’s not able to connect to Blynk, so it keeps on looping the code. It connects to my router normally through normal esp8266 code and the same goes for the Blynk code, but it stops at connecting to blynk-cloud.com:80 and spits out a bunch of stuff.
my Blynk library version is 1.3.2
I tried connecting through a mobile hotspot and through a VPN but it didn’t help.
I saw several places that maybe adding “blynk-cloud.com”, 8080" to my Blynk.begin could help but the outcome stayed the same with or without it
This is my code, it’s a simple example sketch.

#define BLYNK_PRINT Serial
#define BLYNK_TEMPLATE_ID "blahblahblah"
#define BLYNK_TEMPLATE_NAME "blahblahblah"

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = "blahblahblah";
char ssid[] = "UFO";
char pass[] = "blahblahblah";

void setup()
{
  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8080);
}

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

and it spits out this on the serial monitor:

then it loops with the same output every time.

blynk-cloud.com is the URL for the legacy cloud servers, which were decommissioned at the beginning of the year.

Change this to simply:

Blynk.begin(auth, ssid, pass);

or:

Blynk.begin(auth, ssid, pass, "blynk.cloud", 80);

and it should work.

Pete.

In both cases, it still gives out that same output on the serial monitor.

Hello Tstic!

Did you try select NodeMCU 0.9?

What version of the ESP8266 core do you have installed?

What do you see if you run that error through the exception decoder?

Pete.
