# Scanning & Upload - Large report file won't upload

**Symptoms**

* Uploading a large SAST report (for example, a multi-tens-of-megabytes `.fpr`) fails or hangs in the browser.

**Likely cause**

Very large report files can be slow or unreliable to upload through the browser.

**Resolution**

1. Submit the report using the [Mobb CLI](/mobb-user-docs/getting-started/mobb-cli.md) instead of the browser — it handles large reports more reliably.
2. If your SAST tool can export a more targeted report (for example, a single project/module), upload that.
3. If the upload still fails, contact <support@mobb.ai> with the file size and tool version.
