🔧 Vercel Authorization Failure - Troubleshooting Guide

Issue:

  • ❌ Vercel – codely - Authorization required to deploy
  • ❌ Vercel – v0-code-snippets-platform-24 - Authorization required to deploy

Status: Authorization failures blocking deployment
Date: April 26, 2026

🎯 Quick Diagnosis

These errors mean:

  1. Vercel doesn't have permission to deploy from GitHub
  2. OR Vercel GitHub App isn't properly installed
  3. OR Environment variables aren't configured in Vercel
  4. OR Both Vercel projects are out of sync

✅ Solution - Step by Step

STEP 1: Verify Vercel Project Connection (5 minutes)

Go to: https://vercel.com/dashboard

Check:

  1. Is project "codely" connected?
  2. Is project "v0-code-snippets-platform-24" connected?
  3. Are both projects linked to correct GitHub repo?

If not connected:

  • Add new project
  • Select GitHub repo: SudiptaPaul-31/Codely
  • Select framework: Next.js
  • Click "Deploy"

STEP 2: Reconnect GitHub to Vercel (10 minutes)

Option A: Using Vercel Dashboard

  1. Go to: https://vercel.com/account/integrations
  2. Find: "GitHub" integration
  3. Click "Manage"
  4. Check if app is authorized
  5. If not, click "Install" or "Reinstall"
  6. Select repository: SudiptaPaul-31/Codely
  7. Grant all necessary permissions
  8. Authorize

Option B: Reinstall GitHub App

  1. Go to: GitHub Settings → Developer settings → GitHub Apps
  2. Find: "Vercel" app
  3. Click "Edit"
  4. Check permissions (should include "Contents" read/write)
  5. Check "Repository access" includes your repo
  6. If missing, click "Edit" and add your repo

STEP 3: Check Vercel Project Settings (10 minutes)

For EACH project (codely + v0-code-snippets-platform-24):

In Vercel Dashboard:

  1. Open Project Settings
  2. Go to "Git"
  3. Verify:
    • Repository is correct
    • Production branch is correct (usually main)
    • GitHub account is connected
  4. Go to "Environment Variables"
  5. Verify all required variables are set:
    • DATABASE_URL ✅
    • JWT_SECRET ✅
    • NEXT_PUBLIC_STELLAR_NETWORK ✅
    • NEXT_PUBLIC_APP_URL ✅

If variables missing:

  1. Copy from .env.example or your local .env.local
  2. Paste into Vercel Environment Variables
  3. Mark sensitive ones as "Encrypted"
  4. Save

STEP 4: Trigger Redeployment (5 minutes)

After fixing settings:

Option A: Automatic (Recommended)

  1. Make a small commit to repo (or add empty commit)
  2. Push to GitHub
  3. GitHub will trigger Vercel deployment
# Make empty commit to trigger redeployment
git commit --allow-empty -m "trigger deployment"
git push origin main

Option B: Manual in Vercel

  1. Go to Vercel Dashboard
  2. Open project
  3. Click "Deployments"
  4. Find the failed deployment
  5. Click "⋮" (three dots)
  6. Click "Redeploy"

Option C: Manual using Vercel CLI

# Install Vercel CLI if not already installed
npm i -g vercel

# Login to Vercel
vercel login

# Deploy
vercel --prod

STEP 5: Verify GitHub Status Check (5 minutes)

If deployment was triggered via GitHub PR:

  1. Go to your GitHub PR
  2. Scroll to "Checks" section
  3. Wait for Vercel checks to update
  4. Should show ✅ after deployment succeeds

If still failing:

  • Click "Details" on failing check
  • Read error message carefully
  • Go to Vercel dashboard and check build logs

🔍 Detailed Troubleshooting by Issue

Issue 1: "Authorization required to deploy"

Root Cause: Vercel GitHub App not properly authorized

Solutions:

Solution A: Reinstall GitHub App

1. Go to: https://vercel.com/account/integrations/github
2. Click "Manage"
3. Look for your repository
4. If not there, click "Install GitHub App"
5. Select your repo
6. Click "Install"
7. Authorize access

Solution B: Check GitHub OAuth Token

1. Go to GitHub: Settings → Developer settings → Personal access tokens
2. Create new token if needed:
   - Name: "Vercel Deployment"
   - Scope: repo (full control)
   - Copy token
3. Go to Vercel dashboard
4. Account → Integrations → GitHub → "Manage"
5. Paste token if prompted

Solution C: Disconnect and Reconnect

1. Vercel Dashboard → Settings → Integrations
2. Find GitHub integration
3. Click "Disconnect"
4. Click "Connect"
5. Authorize with GitHub
6. Select repositories
7. Complete setup

Issue 2: Multiple Vercel Projects Out of Sync

Root Cause: Both "codely" and "v0-code-snippets-platform-24" projects exist, might be pointing to different branches

Solution:

OPTION A: Use only one project (Recommended)
1. Decide which is the main project
2. Delete the other from Vercel dashboard
3. Keep only one: either "codely" OR "v0-code-snippets-platform-24"

OPTION B: Keep both but configure separately
1. Project 1 (codely):
   - Points to main branch
   - Has all environment variables

2. Project 2 (v0-code-snippets-platform-24):
   - Could point to develop branch (or delete it)
   - Same environment variables

OPTION C: Create alias
1. In main Vercel project
2. Add domain/alias for the second name
3. Delete the redundant project
