# Troubleshooting

The Nextcloud image entrypoint supports a debug (verbose) mode that can be toggled on via an environment variable. This can be used to troubleshoot container start-up, Nextcloud installation, entrypoint changes, etc.

- `IMAGE_DEBUG=1`

Note the container log will be highly verbose with this on!

# Help (Questions / Issues)

**If you have any questions or problems while using the image, please ask for assistance on the Help Forum first (https://help.nextcloud.com)**.
