Server selection timeout: No available servers

Hi all,

I’m running into a problem where my Next.js application cannot connect to my hosted MongoDB instance during build time. Every time that the app hits the compilation step for the ISR pages, I am met with the following error:

I’ve tried playing around with the trusted sources, but my applet is already there and the last successfully deployed instance is still capable of connecting. Additionally I can connect to the database instance both through MongoDB Compass as well as having the application build and run successfully.

For context, I’ve recently transitioned my app from a single Next.js application into a monorepo using Turborepo. My package.json looks like this:

{
  "private": true,
  "workspaces": [
    "packages/*",
    "apps/*",
    "packages/config/*"
  ],
  "license": "UNLICENSED",
  "packageManager": "yarn@1.22.19",
  "scripts": {
    "build": "npm run with-env turbo run build",
    "build:digitalocean": "npm run with-env turbo run build:digitalocean",
    "db:push": "npm run with-env turbo run db:push",
    "db:generate": "turbo run db:generate",
    "start": "npm run with-env turbo run start",
    "dev": "npm run with-env turbo dev --parallel",
    "clean": "git clean -xdf node_modules",
    "clean:workspaces": "turbo clean",
    "lint": "turbo lint && manypkg check",
    "lint:fix": "turbo lint:fix && manypkg fix",
    "format": "prettier --write \"**/*.{js,cjs,mjs,ts,tsx,md,json}\" --ignore-path .gitignore",
    "type-check": "turbo type-check",
    "with-env": "dotenv -e .env --"
  },
  "dependencies": {
    "@ianvs/prettier-plugin-sort-imports": "3.7.1",
    "@manypkg/cli": "^0.20.0",
    "@types/prettier": "^2.7.2",
    "dotenv-cli": "^7.0.0",
    "eslint": "^8.34.0",
    "eslint-config-acme": "0.0.0",
    "prettier": "^2.8.5",
    "prettier-plugin-tailwindcss": "^0.2.5",
    "turbo": "^1.8.3",
    "typescript": "^4.9.5"
  }
}

Any help here would be appreciated, as I have been pulling my hair out trying to figure this out.
