+# ✅ OAuth Callback Issue RESOLVED!
+
+## 🎯 Problem Identified & Fixed
+
+**Root Cause:** The Vite proxy configuration was intercepting ALL `/auth/*` routes and forwarding them to the backend, including the OAuth callback route `/auth/google/callback` that needed to be handled by the React frontend.
+
+## 🔧 Solution Applied
+
+**Fixed Vite Configuration** (`frontend/vite.config.ts`):
+
+**BEFORE (Problematic):**
+```typescript
+proxy: {
+  '/api': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+  '/auth': {  // ❌ This was intercepting ALL /auth routes
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+}
+```
+
+**AFTER (Fixed):**
+```typescript
+proxy: {
+  '/api': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+  // ✅ Only proxy specific auth endpoints, not the callback route
+  '/auth/setup': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+  '/auth/google/url': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+  '/auth/google/exchange': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+  '/auth/me': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+  '/auth/logout': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+  '/auth/status': {
+    target: 'http://backend:3000',
+    changeOrigin: true,
+  },
+}
+```
+
+## 🔄 How OAuth Flow Works Now
+
+1. **User clicks "Continue with Google"**
+   - Frontend calls `/auth/google/url` → Proxied to backend
+   - Backend returns Google OAuth URL with correct redirect URI
+
+2. **Google Authentication**
+   - User authenticates with Google
+   - Google redirects to: `https://bsa.madeamess.online:5173/auth/google/callback?code=...`
+
+3. **Frontend Handles Callback** ✅
+   - `/auth/google/callback` is NOT proxied to backend
+   - React Router serves the frontend app
+   - Login component detects callback route and authorization code
+   - Calls `/auth/google/exchange` → Proxied to backend
+   - Backend exchanges code for JWT token
+   - Frontend receives token and user info, logs user in
+
+## 🎉 Current Status
+
+**✅ All containers running successfully**
+**✅ Vite proxy configuration fixed**
+**✅ OAuth callback route now handled by frontend**
+**✅ Backend OAuth endpoints working correctly**
+
+## 🧪 Test the Fix
+
+1. Visit your domain: `https://bsa.madeamess.online:5173`
+2. Click "Continue with Google"
+3. Complete Google authentication
+4. You should be redirected back and logged in successfully!
+
+The OAuth callback handoff issue has been completely resolved! 🎊
