Problem with connecting to blynk-cloud

Please Help, Im using esp8266 with blink code. It would not connect and I tried different solutions from the internet.
pinging is ok to blynk-cloud.com
I tried Blynk.config( auth, "blynk-cloud.com", 80);
and Blynk.config( auth, "blynk-cloud.com");
and Blynk.begin(auth, ssid, pass, IPAddress(188,166,206,43), 80);
Blynk.begin(auth, ssid, pass, IPAddress(188,166,206,43), 8442);and 8443
Some solutions present the idea of changing the dns and I did not understand how to do it.

What does “ok” mean, what sort of times are you getting?

What happens if you enable Blynk debug:

What do you see in your serial monitor?

I see from your IP address that you’re in Syria. I guess that it’s possible some of the ports used by Blynk may be being blocked by your ISP? In this case, a ping would stil;l work, but Blynk would not.

Are you aware of any other Blynk users in Syria, and if so do they need to use a VPN or a local server?

Pete.

was auth properly assigned a valid auth code ?
