My domain is:www.davidjhindley.com

I ran this command: See below.

It produced this output: See below.

My web server is (include version): 1.10.3-0ubuntu0.16.04.5

The operating system my web server runs on is (include version): Ubuntu 16.04.7

My hosting provider, if applicable, is:Digital Ocean

I can login to a root shell on my machine (yes or no, or I don't know):yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):no

The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you're using Certbot):1.16.0

I recently tried to use "certbot-auto renew" to renew my certificates and got a message telling me certbot auto would no longer work, so I followed the instructions to install certbot via snapd. The new certificates installed correctly, but I now can't load my website. I think it is something to do with my nginx configuration file. I was getting too many redirects, so I removed the return 301 command under the https server part of my "default" file at \etc\nginx\sites-available, and that removed the redirect errors, but I now just get Error 404 not found errors. When I originally installed certbot a few years ago, I think I manually changed some of the nginx configuration file called \etc\nginx\sites-available\default so maybe the changes made automatically when I updated certbot via snapd are conflicting in some way with those manual changes. The current file called "default" stored in \etc\nginx\sites-available\ is shown below.

Any help you can give would be much appreciated.

Many Thanks

David.

Welcome Back to the Let's Encrypt Community, David 🙂

Let's see what we can do to get your nginx configuration cleaned up. Some of what I'm going to ask for might seem redundant, but I need it formatted using the backticks as mentioned at the bottom of this post.

What are the outputs of these commands?

```nohighlight
sudo certbot certificates
sudo ls -lRa /etc/letsencrypt
sudo nginx -T
sudo ls -lRa /etc/nginx/sites-available
sudo ls -lRa /etc/nginx/sites-enabled
sudo cat /etc/nginx/sites-enabled/default

```

Please put 3 backticks above and below _each_ output, like this:

```  
output  
```

The default server config has:

> [@dj\_h](#):
>
> listen 443 ssl http2 default\_server;  
> `server_name _;`  
> `root /var/www/html;`

The config for your site has only:

> [@dj\_h](#):
>
> `listen 443 ssl;`  
> server\_name [davidjhindley.com](http://davidjhindley.com) [www.davidjhindley.com](http://www.davidjhindley.com);

Where is the document root?  
[without which it won't know exactly what to serve when matched]

Thanks for your reply. Here is the requested output (first two to start with - rest in further posts, as was getting formatting issues, so am breaking it up into different posts).

Thanks for posting those. 🙂

1. Replace your existing `default` file in `/etc/nginx/sites-available` with the following file (removing the `.txt` extension of course):

[default.txt](https://community.letsencrypt.org/uploads/short-url/jDY9hyRr5oHOw7D4vHJJYMyms9l.txt) (1.6 KB)

1. Reload nginx.

`sudo nginx -s reload`

1. Test your certificate renewal.

`sudo certbot renew --dry-run`

Did the certificate renewal test succeed?
