如题，我有一个docker容器new-api，宿主机可以ping通，进入docker容器内部的sh终端之后也可以ping通，但是就是显示连不上connect.linuxdo.org 
这是认证代码： 
package controller

import (
        "encoding/base64"
        "encoding/json"
        "errors"
        "fmt"
        "net/http"
        "net/url"
        "strconv"
        "strings"
        "time"

        "github.com/QuantumNous/new-api/model"
