+3. Restart containers: `podman-compose restart`
+4. Check database: `podman exec mold_cost_db pg_isready`
+
+### Database Issues
+1. Check database container: `podman logs mold_cost_db`
+2. Verify connections: `podman exec mold_cost_db psql -U postgres -c "SELECT version();"`
+3. Restore from backup if needed
+4. Run migrations: `flask db upgrade`
+
+### SSL/HTTPS Issues
+1. Check Cloudflare status
+2. Verify certificate expiration
