node.js - MongoDB Atlas - 如何修复共享网络托管上的“TransientTransactionError”

Question

TransientTransactionError尝试从共享网络主机连接到 Mongo Atlas 时

我实际上曾经有过这个工作，但我不得不在我的网络主机上从头开始擦除并重新启动我的项目。现在，在尝试连接到 Atlas 时，我似乎突然出现上述错误。我已经尝试在 Atlas 中将 IP 地址列入白名单，包括我的服务器 IP 和 0.0.0.0/0（“允许所有”通配符）。

我也尝试使用“完整驱动程序”片段而不是猫鼬，但仍然收到相同的错误。最后，我想指出完全相同的代码在我的本地机器上运行良好。

这是我的功能：

    const mongoose = require("mongoose");
    const config = require("./config");
    module.exports = cb => {
        if (mongoose.connection.readyState < 1) {
            mongoose.connect(config.db).then(
                () => {
                    console.log("Database linking successful!");
                    return cb ? cb : null;
                },
                err => {
                console.log("Failed to connect to database.", err);
                }
            );
        }
    };

错误消息如下所示：
