- Cloudflare only supports uploading files up to 100 MB in the free plan, if you try to upload bigger files you will get an error (413 - Payload Too Large) if no chunking is used (e.g. for public uploads in the web, or if chunks are configured to be bigger than 100 MB in the clients or the web). If you need to upload bigger files, you need to disable the proxy option in your DNS settings, or you must use another proxy than Cloudflare tunnels. Both options will disable Cloudflare DDoS protection.
- Cloudflare only allows a max timeout of 100s for requests which is not configurable. This means that any server-side processing e.g. for assembling chunks for big files during upload that take longer than 100s will simply not work. See https://github.com/nextcloud/server/issues/19223. If you need to upload big files reliably, you need to disable the proxy option in your DNS settings, or you must use another proxy than Cloudflare tunnels. Both options will disable Cloudflare DDoS protection.
- It is known that the in AIO included collabora (Nextcloud Office) does not work out of the box behind Cloudflare. To make it work, you need to add all [Cloudflare IP-ranges](https://www.cloudflare.com/ips/) to the wopi-allowlist in `https://yourdomain.com/settings/admin/richdocuments`
- Cloudflare Proxy might block the Turnserver for Nextcloud Talk from working correctly. You might want to disable Cloudflare Proxy thus. See https://github.com/nextcloud/all-in-one/discussions/2463#discussioncomment-5779981
- The built-in High performance backend for Nextcloud Talk will potentially not work out-of-the-box since it needs a separate port (by default 3478 or as chosen) available on the same domain. If you still want to use the feature, you will need to adjust and test your settings in `https://yourdomain.com/settings/admin/talk`.
- If you get an error in Nextcloud's admin overview that the HSTS header is not set correctly, you might need to enable it in Cloudflare manually.
- If you are using AIO's built-in Reverse Proxy and don't use your own, then may the certificate issuing possibly not work out-of-the-box because Cloudflare might block the attempt. In that case you need to disable the Proxy feature at least temporarily in order to make it work. See https://github.com/nextcloud/all-in-one/discussions/1101.
