└────────────────────────────────────────────────────────────────┘
|
|
|
|
1. ✅ WebSocket HTTPS Security Error
|
|
• Root Cause: webpack-dev-server in production build
|
|
• Fix: Rebuilt without dev server, added .env.production
|
|
• Status: RESOLVED
|
|
|
|
2. ✅ Backend Service Failing (Port 8080 Conflict)
|
|
• Root Cause: Rogue python app.py process
|
|
• Fix: Killed process, added pre-start check
|
|
• Status: RESOLVED
|
|
|
|
3. ✅ Dev/Production Conflicts
|
|
• Root Cause: No separation between modes
|
|
• Fix: Enhanced scripts with conflict detection
|
|
• Status: PREVENTED

WebSocket Error:
|
|
• Production build included webpack-dev-server client code
|
|
• Tried to open ws:// connection on HTTPS page
|
|
• Browsers block insecure WebSocket on HTTPS
|
|
|
|
Port Conflict:
|
|
• Development Flask server (python app.py) left running
|
|
• Occupied port 8080, blocking Gunicorn service
|
