hello,

I just tried a new install of discourse on digital ocean. I’m trying to use a subdomain and I believe lestencrypt is putting errors out.

```

```plaintext
DISCOURSE_HOSTNAME: ask.sysadminonlinux.org

```

Hmm.

```plaintext
$ dig +short ask.sysadminonlinux.org
104.131.55.13

```

Is your droplet 104.131.55.13?

If not, that’s the problem. If it is, then, well, maybe it’s something else.

Does the `/var/discourse/shared/standalone/ssl/ask.sysadminonlinux.org.cer` file looks good?
