QUICK FIX FOR NETWORK ERROR:

1. Apply Apache config:
   sudo cp erp.codearya.com.conf /etc/apache2/sites-available/erp.codearya.com.conf
   sudo apache2ctl configtest
   sudo systemctl reload apache2

2. Restart backend:
   pkill -f "erp-backend"
   cd backend && cargo run

3. Test from external network

All fixes are applied in code, just need to restart services!
