# Scanning & Upload - Scan or analysis times out

**Symptoms**

* The analysis runs for a long time and then times out or never completes.

**Likely cause**

Very large codebases/reports, or network conditions (proxies, firewalls, dropped long-lived connections), can cause timeouts.

**Resolution**

1. If you're using the CLI and the run hangs during analysis, use the `--polling` flag so the CLI uses HTTP polling instead of a long-lived WebSocket connection — see the [Mobb CLI Troubleshooting Guide](/mobb-user-docs/getting-started/mobb-cli/troubleshoot.md).
2. Reduce the scope of a single submission where possible (fewer findings / a smaller module).
3. If timeouts persist, contact <support@mobb.ai> with the report ID and approximate size.
