MongooseServerSelectionError:connectECONNREFUSED::1:27017但是我的mongod服務正在運行

每次我在后端檔案夾中運行 npm start 時，我的服務器都會在短時間內成功運行，然后在崩潰后不久。我從命令列收到此錯誤：

這是一張可能有助于解決問題的圖片： 我的 index.js 檔案和 Mongo Compass 的截圖

我是后端 Web 開發的新手，在嘗試學習有關 MERN 的 LINKEDIN LEARNING 課程時遇到此錯誤。鏈接在這里：本課程的視頻 3，非常感謝愿意花時間幫助我解決問題的人，謝謝！

uj5u.com熱心網友回復：

從connect ECONNREFUSED ::1:27017看來，Mongoose 正在嘗試連接到您的螢屏截圖所說mongod的ipv6 ipv4。

使用ipv4即，127.0.0.1
