Hi @Zackie
Welcome to Discourse Meta.
The next logical step would be to follow this install guide:
> [discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/main/docs/INSTALL-cloud.md)
I hope it helps.

I am getting an error while installing discourse
port 443 of computer does not appear to be accessible using hostname: [example.com](http://example.com)
but A connection to port 80 succeeds!
This means DNS settings are correct!
What should I do now ?

Is there a firewall blocking comms on port 443?
You can check the DigitalOcean firewall and your VPS’ firewall to see if that’s the case

I also talked with the domain company and they told me to wait as it can take 24-48 hours to propagate properly. Maybe It will fix the issue

I think it’s easier to install discourse on a subdomain, so [www.example.com](http://www.example.com) (or [forum.example.com](http://forum.example.com), etc) rather than the root of ‘[example.com](http://example.com)’.

but I want to install it on the main domain

That may be a letsencrypt issue. I found this tip quite useful to certify both www and non-www:

> NOTE: @pfaffman says: This page needs to be cleaned up. There is now a new ENV setting that will let you add more hostnames. In your app.yml under your DISCOURSE\_HOSTNAME line (it can go many places but that one makes sense), add DISCOURSE\_HOSTNAME\_ALIASES: domain.com,other.domain.com and early reports suggest that you’ll get valid certs for those domains and that accessing https://domain.com will properly redirect you to your DISCOURSE\_HOSTNAME without a certificate error. If you do that an…

The box says it’s not secure?
To amend your app.yml:
```plaintext
cd /var/discourse
nano containers/app.yml
```
Then use the arrow keys to navigate to the right section, and follow the instructions in the quoted post above.
If it doesn’t work, you can edit it out of your app.yml afterwards, and we can try something else. 🙂
