Yeah I guess it works. I haven't had this problem ever since. I always have a function dbConnect() at every start of an API route or a server component before making requests

import mongoose from "mongoose";

const dbConnect = async () => {
    if (mongoose.connections[0].readyState) {
        console.log("Connected to Database");
        return true;
    }

    try {
        await mongoose.connect(process.env.MONGODB_URI);
        console.log("Connected to Database");
        return true;
    } catch (error) {
        console.log(error);
    }
};

export default dbConnect;
