# Local instance
|
|
It is possible due to several reasons that you do not want or cannot open Nextcloud to the public internet. However AIO requires a valid certificate to work correctly. Below is discussed how you can achieve both: Having a valid certificate for Nextcloud and only using it locally.
|
|
|
|
## 1. The recommended way
|
|
The recommended way is the following:
|
|
1. Set up your domain correctly to point to your home network
|
|
1. Set up a reverse proxy by following the [reverse proxy documentation](./reverse-proxy.md) but only open port 80 (which is needed for the ACME challenge to work - however no real traffic will use this port).
|
|
1. Set up a local DNS-server like a pi-hole and configure it to be your local DNS-server for the whole network. Then in the Pi-hole interface, add a custom DNS-record for your domain and overwrite the A-record (and possibly the AAAA-record, too) to point to the local ip-address of your reverse proxy (see https://github.com/nextcloud/all-in-one#how-can-i-access-nextcloud-locally)
|
|
1. Enter the the ip-address of your local dns-server in the deamon.json file for docker so that you are sure that all docker containers use the correct local dns-server.
|
|
1. Now, entering the domain in the AIO-interface should work as expected and should allow you to continue with the setup
|
|
|
|
## 2. Use the ACME DNS-challenge
|
|
You can alternatively use the ACME DNS-challenge to get a valid certificate for Nextcloud. Here is described how to set it up: https://github.com/nextcloud/all-in-one#how-to-get-nextcloud-running-using-the-acme-dns-challenge
|
|
|
|
## 3. Use Cloudflare
|
|
If you do not have any contol over the network, you may think about using Cloudflare Tunnel to get a valid certificate for your Nextcloud. However it will be opened to the public internet then. See https://github.com/nextcloud/all-in-one#how-to-run-nextcloud-behind-a-cloudflare-tunnel how to set this up.
|
|
|
|
## 4. Buy a certificate and use that
|
|
If none of the above ways work for you, you may simply buy a certificate from an issuer for your domain. You then download the certificate onto your server, configure AIO in [reverse proxy mode](./reverse-proxy.md) and use the certificate for your domain in your reverse proxy config.
