net/http GET request error tls oversized record received with length 20527

I'm stucking to perform a get request using Golang and I also have tried three distinct implementations without success. For all them I'm receiving this error message:

Get https://11.11.11.1:0000/httpgw.conf?Type=SMS&Address=12345678&MsgID=12
3&Notify=N&Validity=24:00&OAdC=15555&Message=HelloBrother: tls: oversized recor
d received with length 20527

Bellow is the entire source code that I'm working on:

    package main
import (
"crypto/tls"
"fmt"
"io/ioutil"
"net/http"
"os"
)
func main() {
cmdSecSMS := "https://11.11.11.1:0000/httpgw.conf?Type=SMS&Address=12345678&MsgID=123&Notify=N&Validity=24:00&OAdC=15555&Message="
msg := "HelloBrother"
cmdSecUrlSMS := cmdSecSMS + msg
doClientTrans(cmdSecUrlSMS)
doGetClient(cmdSecUrlSMS)
doGet(cmdSecUrlSMS)
}
func doClientTrans(address string) {
tr := &http.Transport{
TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
}
client := &http.Client{Transport: tr}
response, err := client.Get(address)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
} else {
defer response.Body.Close()
contents, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
}
fmt.Printf("%s\n", string(contents))
fmt.Println(" Size: ", len(string(contents)), " url: ", address)
fmt.Println(" Status Code:  ", response.StatusCode)
hdr := response.Header
for key, value := range hdr {
fmt.Println(" ", key, ":", value)
}
}
}
func doGet(url string) {
response, err := http.Get(url)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
} else {
defer response.Body.Close()
contents, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
}
fmt.Println(" Size: ", len(string(contents)), " url: ", url)
fmt.Println(" Status Code:  ", response.StatusCode)
hdr := response.Header
for key, value := range hdr {
fmt.Println(" ", key, ":", value)
}
}
}
func doGetClient(url string) {
client := &http.Client{}
response, err := client.Get(url)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
} else {
defer response.Body.Close()
contents, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Printf("%s", err)
os.Exit(1)
}
fmt.Println(" Size: ", len(string(contents)), " url: ", url)
fmt.Println(" Status Code: ", response.StatusCode)
hdr := response.Header
for key, value := range hdr {
fmt.Println(" ", key, ":", value)
}
}
}

When using telnet, this GET request works normally:

telnet 11.11.11.1 0000

Get https://11.11.11.1:0000/httpgw.conf?Type=SMS&Address=12345678&MsgID=12
3&Notify=N&Validity=24:00&OAdC=15555&Message=HelloBrother HTTP/1.1

^:
exit

I'm running the golang app in the windows server 2012 and I don't know nothing about the server tech stack.

It's possible to fix this issue? There is a configuration workaround or something else that I can try?

thanks for your help

I'm glad to share with you that I reach the needed implementation.

The code bellow works!

Thanks for your comments that guide me to the right approach for this task:

package main
import (
"bufio"
"crypto/tls"
"fmt"
"io/ioutil"
"net"
"net/http"
"os"
)
func main() {
cmdSecSMS := "GET https://10.xxx.xx.x:xx43/httpgw.conf?" +
"Type=SMS&Address=5511111&MsgID=123&Notify=N&Validity=24:00&OAdC=15555&" +
"Message=blablah " +
"HTTP/1.1"
fmt.Println(cmdSecSMS)
cmdSecUrlSMS := cmdSecSMS
hostName := "10.xxx.xx.x"
portNum := "xx43"
doDial(cmdSecUrlSMS, hostName, portNum)
//doClientTrans(cmdSecUrlSMS)
//doGetClient(cmdSecUrlSMS)
//doGet(cmdSecUrlSMS)
}
func doDial(cmd, host, port string) {
// connect to this socket
conn, err := net.Dial("tcp", host+":"+port)
if err != nil {
fmt.Printf("Some error %v", err)
return
} else {
defer conn.Close()
fmt.Printf("Connection established between %s and localhost.\n", host)
fmt.Printf("Local Address : %s \n", conn.LocalAddr().String())
fmt.Printf("Remote Address : %s \n", conn.RemoteAddr().String())
// send to socket
fmt.Fprintf(conn, cmd+"\n")
// listen for reply
message, _ := bufio.NewReader(conn).ReadString('\n')
fmt.Print("Message from server: " + message)
}

}

Thank you guys for your support!
