It seems you’re encountering issues with thumbnail previews in your Nextcloud installation. If you’re using a **TurnKey Linux template inside a Proxmox LXC container** , this setup can introduce various limitations — and thumbnail generation problems might be one of them.

We discussed the risks of using TurnKey templates for Nextcloud in more detail here:  
👉 [Is there limitations to installing Nextcloud via CT template on Proxmox?](https://help.nextcloud.com/t/is-there-limitations-to-installing-nextcloud-via-ct-template-on-proxmox/222997)

These templates often come with outdated or misconfigured components (like PHP or image processing libraries), which can break or limit core Nextcloud features — including thumbnail generation for image files.

💡 **Recommended setup** : A **Proxmox VM running Ubuntu Server 24.04** with **Nextcloud All-in-One (AIO)** installed via Docker offers a much more stable and compatible environment.

✅ In this setup, **thumbnail generation for image files works perfectly out of the box** — no tweaks or manual fixes needed.

This approach provides full compatibility with all Nextcloud features, reliable updates, and long-term maintainability, without the hidden pitfalls of container templates.
