Renew SSL for ghost sites on DigitalOcean

So earlier this year my 2 Ghost sites on my DO server had their SSL expire. I tried everything suggested at How to renew default let's encrypt ssl? and it did not work.

So I set up the entire server again. Now the same issue. The SSL did not auto-renew and I can’t seem to find a way to renew them.

Does anyone have any steps to debug?

I first ran this command:
“/etc/letsencrypt”/acme.sh --upgrade --home “/etc/letsencrypt”
The results were:
[Sat Oct 17 07:22:21 UTC 2020] Already uptodate!
[Sat Oct 17 07:22:21 UTC 2020] Upgrade success!

Than I entered:
“/etc/letsencrypt”/acme.sh --cron --home “/etc/letsencrypt” > /dev/null

The results were:
[Sat Oct 17 07:31:42 UTC 2020] stretch.themeist.com:Verify error:Invalid response from http://stretch.themeist.com/.well-known/acme-challenge/FHhS6J7YH4VOnoTf9WI7gdJcxmXOoj75xwuKfNsmr8s [164.90.196.33]:

I followed the steps listed on `ghost setup ssl`: Error, can not get domain token entry.

It renews the first domain setup when I created the DO. But I still get the same error for the 2nd domain I have created using ghost CLI.

When I use the following command, I get this error:

Based on my understanding of this error, it looks like the SSL was not setup for the 2nd website I setup. But if that is the case then how did SSL did work until it expired.
