Webhook http to telegram.How to be?

Hi all. I have a problem(probably like I'm a million,but the solution is not was able to find).
Telegrams can not send me the data(webhook).
Does telegrammy webhook for IP addresses?
tried to send myself the data to check,does my script data
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://мой IP :8443/out/api/bot.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "postvar1=value1&postvar2=value2&postvar3=value3");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec ($ch);
curl_close ($ch);

my code successfully got all the data.
telegram in response, writes the following
"last_error_message":"Write timeout expired","max_connections":40}}
.Could it be because of the forwarding on the router?(incoming 8443 to port 80 of server)

First paragraph:
You need a valid SSL certificate for webhooks to work.
However, I don't have a certificate. - nikita.Stracke commented on June 5th 19 at 22:00
