You can fix this by setting up your own reverse proxy that handles TLS proxying locally. +- Cloudflare Proxy and Cloudflare Tunnel both require Cloudflare to perform TLS termination on their side and thus decrypt all the traffic on their infrastructure. This is a privacy concern and you will need to look for other solutions if it's unacceptable for you. +- Using Cloudflare Tunnel might potentially slow down Nextcloud since local access via the configured domain is not possible because TLS termination is in that case offloaded to Cloudflare's infrastructure. There is no way to disable this behavior in Cloudflare Tunnel. - It is known that the domain validation may not work correctly behind Cloudflare since Cloudflare might block the validation attempt. You can simply skip it in that case by following: https://github.com/nextcloud/all-in-one#how-to-skip-the-domain-validation - Make sure to [disable Cloudflares Rocket Loader feature](https://help.nextcloud.com/t/login-page-not-working-solved/149417/8) as otherwise Nextcloud's login prompt will not be shown. -- 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 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).

Note that this will both disable Cloudflare DDoS protection and Cloudflare Tunnel as these services require the proxy option to be enabled. - 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 turn-server for Nextcloud Talk will not work behind Cloudflare Tunnel 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 install your own turnserver or use a publicly available one and adjust and test your stun and turn 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.

In that case you need to disable the Proxy feature at least temporarily in order to make it work. Note that this isn't an option if you need Cloudflare Tunnel as disabling the proxy would also disable Cloudflare Tunnel which would in turn make your server unreachable for the verification. See https://github.com/nextcloud/all-in-one/discussions/1101. ### How to run Nextcloud behind a Cloudflare Tunnel? Although it does not seems like it is the case but from AIO perspective a Cloudflare Tunnel works like a reverse proxy. So please follow the [reverse proxy documentation](./reverse-proxy.md) where is documented how to make it run behind a Cloudflare Tunnel. However please see the [caveats](https://github.com/nextcloud/all-in-one#notes-on-cloudflare-proxytunnel) before proceeding.
