unable to detect btcd version

[nguyenHoang32]

Getting the block count was successful. Block: 861271.
However, when I call client.GetBlockChainInfo(), I get an error: "Unable to detect btcd version. Status code: 403, response: ''".

`package main

import (
"fmt"
"log"

"github.com/btcsuite/btcd/rpcclient"

)

func main() {
// RPC server details
username := "1"
password := "1"

// Create a new RPC connection configuration
connCfg := &rpcclient.ConnConfig{
	Host:         "go.getblock.io/66247efe0af84dfab9814fc368fb473a",
	User:         username,
	Pass:         password,
	HTTPPostMode: true,
	DisableTLS:   false, // Set to true if you don't use TLS
}
fmt.Println(connCfg.Host)
// Create a new RPC client
client, err := rpcclient.New(connCfg, nil)
if err != nil {
	log.Fatalf("Error creating new RPC client: %v", err)
}
defer client.Shutdown()
block, err := client.GetBlockCount()
fmt.Println("Block", block)
if err != nil {
	log.Fatalf("Error retrieving blockchain info: %v", err)
}
// Retrieve blockchain info
blockchainInfo, err := client.GetBlockChainInfo()
if err != nil {
	log.Fatalf("Error retrieving blockchain info: %v", err)
}

// Print blockchain info
fmt.Printf("Chain: %s\n", blockchainInfo.Chain)

}
