+# Frontend Deployment Check & Fix
+
+## Issue
+Seeing "DBIS Core Banking System - Frontend application deployment pending" on refresh.
+
+## Root Cause
+This message appears when:
+1. The frontend hasn't been built (`dist/` folder doesn't exist or is empty)
+2. Nginx is pointing to the wrong directory
+3. The build failed during deployment
+
+## Solution
+
+### Step 1: Check if Frontend is Built
+
+If you're on the deployment container (VMID 10130):
+
+```bash
+# Check if dist folder exists
+ls -la /opt/dbis-core/frontend/dist/
+
+# Check if it has content
+ls -la /opt/dbis-core/frontend/dist/ | head -20
+```
+
+### Step 2: Build the Frontend
+
+If the `dist/` folder is missing or empty, build the frontend:
+
+```bash
+cd /opt/dbis-core/frontend
+
+# Install dependencies (if needed)
+npm install
+
+# Build the application
+npm run build
+```
+
+### Step 3: Verify Nginx Configuration
+
+Check that nginx is pointing to the correct directory:
+
+```bash
+# Check nginx config
+cat /etc/nginx/sites-available/dbis-frontend | grep root
+
+# Should show:
+# root /opt/dbis-core/frontend/dist;
+```
+
+### Step 4: Restart Nginx
+
+After building, restart nginx:
+
+```bash
+systemctl restart nginx
+systemctl status nginx
+```
+
+### Step 5: Verify Build Output
+
+Check that index.html exists in dist:
+
+```bash
+ls -la /opt/dbis-core/frontend/dist/index.html
+cat /opt/dbis-core/frontend/dist/index.html | head -10
+```
+
+## Quick Fix Script
+
+Run this on the frontend container (VMID 10130):
+
+```bash
+#!/bin/bash
+cd /opt/dbis-core/frontend
+
+# Check if node_modules exists
+if [ ! -d "node_modules" ]; then
+    echo "Installing dependencies..."
+    npm install
+fi
+
+# Build the application
+echo "Building frontend..."
+npm run build
+
+# Verify build
+if [ -f "dist/index.html" ]; then
+    echo "✅ Build successful!"
+    echo "Restarting nginx..."
+    systemctl restart nginx
+    echo "✅ Frontend should now be accessible"
+else
+    echo "❌ Build failed - check errors above"
+    exit 1
+fi
+```
+
+## From Proxmox Host
+
+If you need to run this from the Proxmox host:
+
+```bash
+# SSH into the container
+pct exec 10130 -- bash
+
+# Then run the build commands above
+```
+
+Or run directly:
+
+```bash
+pct exec 10130 -- bash -c "cd /opt/dbis-core/frontend && npm run build && systemctl restart nginx"
+```
+
+## Troubleshooting
+
+### Build Errors
+
+If `npm run build` fails:
+1. Check Node.js version: `node --version` (should be 18+)
+2. Check for TypeScript errors
+3. Check for missing dependencies
+4. Review build output for specific errors
+
+### Nginx Errors
+
+If nginx fails to start:
+1. Test config: `nginx -t`
+2. Check logs: `journalctl -u nginx -n 50`
+3. Verify directory permissions
+
+### Still Seeing Placeholder
+
+If you still see the placeholder message:
+1. Clear browser cache
+2. Check browser console for errors
+3. Verify you're accessing the correct IP/URL
+4. Check nginx access logs: `tail -f /var/log/nginx/access.log`
