Can't connect to api.telegram.org

[anmorfe]

Hello;

I have been trying your code but it seems that can't connect to api.telegram.org. I show you a screen capture of serial monitor:

I have tried to use client_tcp.setInsecure(); but it takes an error....

Could you help me....

WiFiClientSecure client_tcp;
client_tcp.setInsecure(); //add the code

I write the code
WiFiClientSecure client_tcp;
client_tcp.setInsecure(); //add the code

But still cannot connect with telegram 😰

Hi
I just try your code and it works well.

[Emb-Coder]

same problem ! i can connect only when i send a message. Not connecting while sending the picture...

Hi, I'm not sure what the problem is. Could you install the version of arduino core for ESP32 to 1.0.6 or 1.0.4 and try again?

I found the issue. It is not due to the software. My power supply didn't provide enough current. I changed it with a higher current one and it now works.
