Let's Encrypt Installation (SSL)

1) Run the following command to allow the connection via the domain example.com to your NextCloud

nextcloud.occ config:system:set trusted_domains 1 --value=example.com

Replace example.com with your domain

2) Enable SSL and request a Let’s Encrypt SSL certificate:

nextcloud.enable-https lets-encrypt

3) The following message will appear, confirm it by pressing y on your keyboard:

In order for Let's Encrypt to verify that you actually own the
domain(s) for which you're requesting a certificate, there are a
number of requirements of which you need to be aware:

1. In order to register with the Let's Encrypt ACME server, you must
   agree to the currently-in-effect Subscriber Agreement located
   here:

       https://letsencrypt.org/repository/

   By continuing to use this tool you agree to these terms. Please
   cancel now if otherwise.

2. You must have the domain name(s) for which you want certificates
   pointing at the external IP address of this machine.

3. Both ports 80 and 443 on the external IP address of this machine
   must point to this machine (e.g. port forwarding might need to be
   setup on your router).

Have you met these requirements? (y/n)

4) Enter your email address when asked to do so and confirm by pressing Enter:

Please enter an email address (for urgent notices or key recovery): user@domain.com

5) Enter the domain name that you have configured in a previous step for your instance (your.domain.com in our case), then confirm by pressing Enter:

Please enter your domain name(s) (space-separated): example.com
