Use Let's Encrypt to Renew SSL Certificates

Starting with Version 19.3, FileCloud supports auto-renewing SSL certificates with Let's Encrypt.

To auto-renew your SSL certificate, you must first contact the Let's Encrypt team.

To use Let's Encrypt's HTTP-01 challenge for adding/renewing SSL certificates:

Contact the Let's Encrypt team and request auto-renewal of your SSL certifcate.

Open the following file:

```
Windows:  C:\xampp\htdocs\.htaccess
```
```
Linux: /var/www/html/.htaccess
```

Find the following code:

#--------------------------------------------------
# Let's Encrypt Support
# RewriteRule ^.well-known/(.*)$ .well-known/$1 [L]
#--------------------------------------------------

Remove # in front of:

RewriteRule ^.well-known/(.*)$ .well-known/$1 [L]

so that the code appears as:

#--------------------------------------------------
# Let's Encrypt Support
RewriteRule ^.well-known/(.*)$ .well-known/$1 [L]
#--------------------------------------------------

Save and close .htaccess.
