-## Troubleshooting
-
-### Ollama models not showing in dropdown (Docker)
-
-If you're running Ollama on your host machine and Sim in Docker, change `OLLAMA_URL` from `localhost` to `host.docker.internal`:
-
-```bash
-OLLAMA_URL=http://host.docker.internal:11434 docker compose -f docker-compose.prod.yml up -d
-```
-
-See [Using an External Ollama Instance](#using-an-external-ollama-instance) for details.
-
-### Database connection issues
-
-Ensure PostgreSQL has the pgvector extension installed. When using Docker, wait for the database to be healthy before running migrations.
-
-### Port conflicts
-
-If ports 3000, 3002, or 5432 are in use, configure alternatives:
-
-```bash
-# Custom ports
-NEXT_PUBLIC_APP_URL=http://localhost:3100 POSTGRES_PORT=5433 docker compose up -d
-```
