|
||||
|
||||
## TROUBLESHOOTING
|
||||
|
||||
**Frontend won't start:**
|
||||
```bash
|
||||
cd grimlock/frontend
|
||||
rm -rf node_modules package-lock.json
|
||||
npm install
|
||||
npm run dev
|
||||
```
|
||||
|
||||
**Backend not responding:**
|
||||
```bash
|
||||
cd grimlock
|
||||
docker-compose down
|
||||
docker-compose up -d
|
||||
curl http://localhost:8000/api/health
|
||||
```
|
||||
|
||||
**WebSocket not connecting:**
|
||||
- Check backend is running
|
||||
- Check .env.local has correct API_URL
|
||||
- Check browser console for errors
|
||||
- Try hard refresh (Cmd+Shift+R)
|
||||
|
||||
**Can't login:**
|
||||
- Check backend logs: `docker-compose logs backend`
|
||||
- Verify user was created in DB
|
||||
- Check JWT token in localStorage
|
||||
- Clear localStorage and try again
