# Ubuntu 16.04
### Enabling HTTPS - Nginx
This example is specifically for Ubuntu 16.04 with Nginx and uses an SSL certificate from Let's Encrypt.
Please follow [this](https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04) excellent tutorial on setting up nginx with an SSL cert from LetsEncrypt.
#### Step 1
Follow the LetsEncrypt tutorial until you get to *Step 2: Obtain and SSL Certificate.*
In this section you need to change some config in the Nginx configuration. The tutorial directs you to edit `/etc/nginx/sites-available/default` however in the standard LibreNMS install, the file you need to edit is actually `/etc/nginx/conf.d/librenms.conf`.
#### Step 2
When you get to *Step 3: Configure TLS/SSL on Web Server (Nginx)* there are some differences again.
Follow the instructions regarding the "snippet" configuration, the main differences come when you get to *Adjust the Nginx Configuration to Use SSL*.
Here you are again directed to edit `/etc/nginx/sites-available/default`, so we need to go to `/etc/nginx/conf.d/librenms.conf`.
`sudo vi /etc/nginx/sites-available/default`
The top section of this file will look like this:
```
server {
listen 80;
listen [::]:80;
server_name example.com;
root /opt/librenms/html;
index index.php;
access_log /opt/librenms/logs/access_log;
error_log /opt/librenms/logs/error_log;
```
Edit it to look like this (obviously changing example.com to your actual domain name):
```
server {
listen 80;
listen [::]:80;
server_name example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
include snippets/ssl-example.com.conf;
include snippets/ssl-params.conf;
server_name example.com;
root /opt/librenms/html;
index index.php;
access_log /opt/librenms/logs/access_log;
error_log /opt/librenms/logs/error_log;
```
This config will redirect HTTP traffic to HTTPS and use the SSL config that you have just set up.
Check for syntax errors
`sudo nginx -t`
Then restart Nginx
`sudo systemctl restart nginx`
#### Step 3
Follow the rest of the tutorial, especially if you have the server's firewall enabled.
