您好我想使用网络作业来调用以下代码：
using (SqlConnection con = new SqlConnection(ConfigStore.RemoteConnectionString()))
{
using (SqlCommand cmd = new SqlCommand(xxxxxx, con))
{
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
if (!reader.HasRows)
{
}
while (reader.Read())
{
}
reader.Close();
}
}
我收到以下错误

我如何确保 azure 可以连接到这个远程 sql 框？
我如何在不影响安全性的情况下实现这一目标？
非常感谢
