I’m getting this message: no working IP addresses found for "[domain.com](http://domain.com)" This is the command I’m running: sudo certbot certonly --standalone -d [domain.com](http://domain.com) I’m not seeing other people having the same problem, am I doing something obviously wrong? Thanks! ---

I’m following instructions I found online, I don’t recall making a config file. Should it be here? /etc/letsencrypt/cli.ini ---

I’m not running a webserver, I thought the --standalone told certbot to spin up it’s own webserver or something like that? ---

> [@justinjja](#): > > I'm not running a webserver, I thought the --standalone told certbot to spin up it's own webserver or something like that? It does, but it so happens that Certbot only added IPv6 support in `--standalone` a week ago, thanks to efforts by @erica. > > > As far as I can tell, the letsencrypt client does not bind to ipv6 in standalone… mode nor do the commands given in manual mode. While this may not seem too significant, but for people with ipv6 only machines (like me) this is quite a big problem. My suggestion would be to somehow bind to both ipv4 and ipv6 at the same time. > > Either way, what you're doing is a great service to the global internet community, keep on rocking! Since you're not running `certbot-auto`, you probably don't have a recent enough version of Certbot to have IPv6 support with `--standalone`, due to this bug. If you install another copy of Certbot with the `certbot-auto` method, you should. > **[Certbot](https://certbot.eff.org/)** > > Tagline @rg305's suggestion is right for selecting a port number (443 vs. 80), but I suspect there's also a deeper problem at work here. 🙂 ---

Nice of @erica to release that feature just in time for me. 😀 Latest version on Ubuntu is apt-get is 14.2, I tried the certbot-auto and it worked fine. Awesome, thanks! ---
