I'm facing issues in generating Letsencrypt SSL certificates for a domain mapped to a private address. (192.168.19.15) My domain is: [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) and its a public domain (Verified from [DNS Checker - DNS Check Propagation Tool](https://dnschecker.org/#A/elk.internal.mindcurv.com)) > jerald@jeraldsm:~$ nslookup [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) > Server: 127.0.0.53 > Address: 127.0.0.53#53 > > Non-authoritative answer: > Name: [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) > Address: 192.168.19.15 I ran this command for generating SSL certificate: ./letsencrypt-auto certonly --standalone -d [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) **It produced the following output:** > [root@elk-slreport letsencrypt]# ./letsencrypt-auto certonly --standalone -d [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) > Saving debug log to /var/log/letsencrypt/letsencrypt.log > Plugins selected: Authenticator standalone, Installer None > Obtaining a new certificate > Performing the following challenges: > http-01 challenge for [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) > Waiting for verification... > Challenge failed for domain [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) > http-01 challenge for [elk.internal.mindcurv.com](http://elk.internal.mindcurv.com) > Cleaning up challenges > Some challenges have failed. > > IMPORTANT NOTES: > > - The following errors were reported by the server: I have also tried using the command "cerbot --apache".

As an alternative, if you like split-horizon DNS, you could potentially set something up where `elk.internal.mindcurv.com` has a routable IP in the external view. E.g. the machine’s own IP, or another machine running a reverse proxy web server… I’m not endorsing it, just saying you have options. Increasingly complicated and customized options. ---
