I’ve just done a clean install, and installed the following on a Raspberry Pi 3:
ProFTP
NextCloud
LAMP
CertBot
Fail2Ban
All went well and was working fine.
I ran dietpi-letsencrypt and setup [http://www.mydomain.com](http://www.mydomain.com)
and everything was fine.
I ran dietpi-letsencrypt again with [mydomain.com](http://mydomain.com)
All was good, but [http://www.mydomain.com](http://www.mydomain.com) stopped working.
So I tried entering two entries into dietpi-letsencrypt, i.e. “[mydomain.com](http://mydomain.com) [http://www.mydomain.com](http://www.mydomain.com)” without the quotes.
This created an error, and now apache2 is not starting up, I get the following error
```nohighlight

1. any idea how I can get apache2 working again
2. How do I set up lets encrypt properly with [http://www.mydomain.com](http://www.mydomain.com) and [mydomain.com](http://mydomain.com)?
Thanks.

I’ll need to see the apache2 config files to see whats up, please paste results of:
```plaintext
cat /etc/apache2/apache2.conf
cat /etc/apache2/sites-available/000-default.conf
```

Having seen these files I have now fixed the issue, the commented line in /etc/apache2/sites-available/000-default.conf was the original line and the line below is my edit. Thanks many thanks for your help.

Hi Keith,
Great to hear its all working.
I checked the source code on this, dietpi-letsencrypt should replace the default site entry if it already exists:
[https://github.com/Fourdee/DietPi/blob/master/dietpi/dietpi-letsencrypt#L100-L113](https://github.com/Fourdee/DietPi/blob/master/dietpi/dietpi-letsencrypt#L100-L113)
Can you remember what value you used exactly for the Domain name input box entry? eg: was it [http://www.mydomain.com](http://www.mydomain.com) or [mydomain.com](http://mydomain.com)?
Thanks Keith

Hi Keith,
I think I know what went wrong here, I’ve updated the code in v134 that should prevent the issue you experienced from occurring again:
> DietPi-LetsEncrypt | Resolved an issue where an empty string value in Input\_Box function could cause a incorrect value being set in Apache2 confs.

It was probably my own fault, I put both options in separated by a space
