Connection Refused Error

curl: (7) Failed to connect to xx.xx.xx.xxx port 80: Connection refused

I installed the droplet and setup everything properly and the forum was working perfectly fine, until I tried to add SSL to the site by following this tutorial: https://meta.discourse.org/t/allowing-ssl-https-for-your-discourse-docker-setup/13847

After completing the process, I returned to my forum and since the site was unreachable showing: curl: (7) Failed to connect to forum.waituk.com port 80: Connection refused

After spending whole night, I finally gave and recreated the app with One Click Install offered by Digital Ocean. I got new IP and completed everything in the One Click Install and then received following confirmation:

Thanks! Your Discourse instance is now being configured…this can take a few minutes…

If you need to re-run this script, run: bash /var/lib/digitalocean/discourse.sh

Failed to stop lighttpd.service: Unit lighttpd.service not loaded. Failed to execute operation: No such file or directory Failed to start docker.service: Unit docker.service not found. Device “docker0” does not exist. Docker is not installed, you will need to install Docker in order to run Launcher See https://docs.docker.com/installation/ /var/lib/digitalocean/discourse.sh: line 70: docker: command not found /var/lib/digitalocean/discourse.sh: line 71: docker: command not found

Now you will be prompted to set your admin password. When prompted put ‘xxx@xxx.com’ as for the admin

And I notice the docker is missing and I am still getting the same error:

curl: (7) Failed to connect to xx.xx.xx.xxx port 80: Connection refused

So, I destroyed and created new droplet and I still got curl: (7) Failed to connect to xx.xx.xx.xxx port 80: Connection refused

Then I deactivated my whole account and signed for new account. And recreated everything from scratch, and I am still getting: curl: (7) Failed to connect to xx.xx.xx.xxx port 80: Connection refused

Even without installing anything, when I check the IP, I keep getting curl: (7) Failed to connect to xx.xx.xx.xxx port 80: Connection refused

Any help?
