# Content and media problems

> Fix document upload, extraction, image, and visual-content issues.

## Cloud

* Confirm the source uses a supported format and is not password protected.
* Convert older office files to a current format before uploading.
* Use a text-based or higher-quality scan when extraction misses content.
* Check that important data is clear and consistently labeled in the source.

## Self-hosted

* Confirm the upload and persistent-data directories are writable.
* Check document-processing logs for parser, OCR, file-size, or timeout errors.
* Verify image and search provider credentials independently from the text provider.
* For host services such as Ollama, use a hostname reachable from the container rather than container `localhost`.
* Convert `.doc`, `.ppt`, and `.xls` files to modern equivalents when parsing fails.

Never share a source document with support unless it is safe to disclose.
