+title: Troubleshooting guide
+description: Solutions for common CodeGate issues
+sidebar_position: 40
+---
+
+This guide provides solutions for common issues you might encounter when using
+CodeGate with various AI coding assistants and agents.
+
+## General troubleshooting steps
+
+Before diving into specific issues, try these general troubleshooting steps:
+
+1. **Check logs**: Run `docker logs codegate` to view recent logs or
+   `docker logs --follow codegate` to watch logs in real-time.
+
+2. **Increase log verbosity**: Restart CodeGate with increased logging level:
+
+   ```bash
+   docker rm -f codegate
+   docker run --name codegate -d -p 8989:8989 -p 9090:9090 -p 8990:8990 \
+     -e CODEGATE_APP_LOG_LEVEL=DEBUG \
+     --mount type=volume,src=codegate_volume,dst=/app/codegate_volume \
+     --restart unless-stopped ghcr.io/stacklok/codegate:latest
+   ```
+
+3. **Verify connectivity**: Ensure the CodeGate API is accessible:
+
+   ```bash
+   curl http://localhost:8989/health
+   ```
+
+4. **Check version**: Ensure you're running the latest version of CodeGate:
+
+   ```bash
+   docker pull ghcr.io/stacklok/codegate:latest
+   ```
+
+## Muxing issues
+
+### "Provider models could not be found" error
+
+This error might occur when adding a new provider or updating an existing one.
+It indicates that CodeGate is unable to discover the available models for the
+provider.
+
+**Possible causes:**
+
+- The provider API endpoint is incorrect
+- The provider is not running or accessible
+- Your API key is invalid or missing
+
+**Solutions:**
+
+1. Verify the provider API endpoint is correct in the CodeGate settings
+2. Ensure the provider is running and accessible from the CodeGate container
+3. For local providers (Ollama, LM Studio), ensure you're using
+   `http://host.docker.internal` instead of `localhost`
+4. Check your authentication credentials (API key) for the provider
+5. Check the logs for specific error messages related to the provider connection
+
+### File pattern matching problems
+
+If your file patterns aren't matching as expected:
+
+1. Use wildcards appropriately: `*.js` matches only `.js` files, while `*.js*`
+   matches both `.js` and `.jsx`
+2. For nested directories, patterns only match the filename, not the path
+3. Test your patterns with simple rules first before creating complex
+   configurations
+4. If a specific file is causing issues, try a more specific rule for that file
+   type
+
+## Dashboard issues
+
+### Dashboard not showing events or alerts
+
+If events or alerts are not appearing in the dashboard:
+
+1. Verify you're looking at the correct workspace
+2. Check if the events were recorded by examining the logs
+3. Try switching workspaces and then switching back
+4. Restart the CodeGate container if the issue persists
+
+### "An error occurred" message
+
+If the dashboard fails to load or shows an error:
+
+1. Refresh the page to see if it resolves the issue
+2. Ensure the CodeGate API is accessible:
+
+   ```bash
+   curl http://localhost:8989/health
+   ```
+
+3. Verify the database is not corrupted by checking the logs
+4. If you are running CodeGate remotely, ensure `DASHBOARD_BASE_API_URL` is
+   correctly set to point to your CodeGate API (see
+   [run CodeGate on a remote host](./configure.md#run-on-remote-host))
+
+If you're still experiencing issues, open an issue on GitHub with details about
+the problem, including logs and steps to reproduce. It's also helpful to include
+details from the Developer Tools in your browser (usually accessible with F12)
+to see if there are any network errors or JavaScript errors in the console.
+
+## CLI and configuration issues
+
+### CLI not responding until model is online
+
+The CodeGate CLI may appear to hang when using local models that need to be
+loaded.
+
+**Solutions:**
+
+1. Check if you're using a local model provider like Ollama that may be loading
+   a model
+2. Verify the model server is running and accessible
+3. Consider using a different model that loads faster for CLI operations
+4. Increase the log level to DEBUG to see what's happening during the delay
+
+### Workspace management issues
+
+If you're having trouble with workspaces:
+
+1. Ensure you're activating the correct workspace before starting work
+2. Use `codegate workspace list` to verify available workspaces
+
+## Network and connectivity issues
+
+### Remote host configuration
+
+If you're running CodeGate on a remote host:
+
+1. Ensure you've set `DASHBOARD_BASE_API_URL` correctly to point to your
+   CodeGate API
+2. Verify that your firewall allows connections to the required ports
+3. For Copilot integration, ensure the HTTPS proxy port is accessible and the
+   certificate is trusted
+
+### Docker networking issues
+
+If you're experiencing networking issues with Docker:
+
+1. Verify that the container ports are correctly mapped to your host
+2. For local providers like Ollama, ensure `host.docker.internal` resolves
+   correctly
+3. On Linux, you may need to add `--add-host=host.docker.internal:host-gateway`
+   to your `docker run` command
+
