HTTP send errno -1163019603

[isurki]

Dear Community;

I am using this code provided by a Nordic engineer to make some HTTP request in order to use Telegram Bot API. It works fine but after 1-2 days working I am getting an error at this part of the code: 

int num_bytes = send(client_fd, send_buf, send_data_len, 0);
if (num_bytes < 0) {
	printk("send errno: %d\n", errno);
	goto clean_up;
}

This is the error: "send errno: -1163019603"

The problem is that after first time this happens never recovers its normal functionality.

What is causing this error? How can be solved?

Any idea or suggestion is welcomed. Thanks.

Hello,

Are you by any chance using an iBasis SIM?

Hi;

I am using Hologram IoT SIM.

It works fine but after 1-2 days working I am getting an error at this part of the code:

 Does it work again after you reset the device?

[isurki]

No, it does not work any more. I have tried to reset the device and also to re-upload the merged.hex but nothing has changed.

What if you change SIM?

We have tried with 3 different Hologram SIMs and does not work. We have also verified that the problem is not the SIM, because we have successfully sent a Telegram message using a Raspberry+IOT modem + Hologram SIM.
