我正在使用它来连接mongodb。在之前的比赛中，我已经完美地运行了它，但在我关闭终端并运行它一个增益后，我出现了错误。
+这是我的代码
async function loadTasksCollection(){
const url="mongodb+srv://user:password@mytasklist.a75ix.mongodb.net/mytasklist?retryWrites=true&w=majority";
const client=new MongoClient(url,{useNewUrlParser:true,useUnifiedTopology: true});
try {
await client.connect();
console.log("sucess")
} catch (error) {
console.log(error);
}
return client.db("tasklist").collection("task");
}
// to read the task
router.get('/',async(req,res)=>{
const task= await loadTasksCollection()
res.send(await task.find({}).toArray())
});
+这是第一个erorr

}
+几秒钟后，我得到了这个

我找到了解决方案，因为我关闭了我的计算机并再次打开它，我的IP地址也发生了更改，但我忘记更改Mongodb图谱中的网络访问IP地址。因为这只是一个惯例，所以现在我将网络访问IP地址更改为公共地址，这样我就再也不会面临这个问题了在此处输入图像描述
