I am using telegram.php to connect my bot. When I use sendmessage all of thing is ok in my logs but I do not receive anything from the bot.

When I check my log there is a problem like this:

curl_error_code:        51
curl_error:     SSL: no alternative certificate subject name matches target host name 'api.telegram.org'

    I don’t know this telegram bot, but I see that it uses GuzzleHttp.
    During the initialization it doesn’t accept any configuration Request::initialize()

    public static function initialize(Telegram $telegram)
{
    if (!($telegram instanceof Telegram)) {
        throw new TelegramException('Invalid Telegram pointer!');
    }
    self::$telegram = $telegram;
    self::setClient(new Client(['base_uri' => self::$api_base_uri]));
}

    you should check its documentation. I see that there are a lot of setters which makes you able to overwrite the default settings.

    What you need is to set the the GuzzleHttpRequestOptions::VERIFY to false in the client config:

    $this->client = new GuzzleHttpClient([
    'base_uri'                          => 'someAccessPoint',
    GuzzleHttpRequestOptions::HEADERS => [
        'User-Agent' => 'some-special-agent',
    ],
    'defaults'                          => [
        GuzzleHttpRequestOptions::CONNECT_TIMEOUT => 5,
        GuzzleHttpRequestOptions::ALLOW_REDIRECTS => true,
    ],
    GuzzleHttpRequestOptions::VERIFY  => false,
]);
