This doesn’t give you any valuable information. Port 8442 is blocked in-bound by your router as expected. This has nothing to do with connecting to Blynk.
Just to make sure we are all on the same page - you have esp8266 connecting to “klg” wi-fi network and you have your phone or computer connected to the same wireless network and from that secondary device you are able to ping blynk-cloud.com? Is this the case?
Can you put in you code, just before
Blynk.config(auth) the following:
this way we are going to see what IP address you are trying to connect to…and, please comment all your libraries except <ESP8266WiFi.h> and <BlynkSimpleEsp8266.h>
