The only things with the word forum (I deleted the AAAA already):

When I try to create it I get this:

I guess I will have to delete the A record with the name `www.forum`? If so, what about the other A record?

I will check that. Let’s see if I can follow it…

What’s weird is that for example `http://www.forum.alltiago.com` works when Chrome is _not_ in incognito, but stops working when it is.  
`www.forum.alltiago.com` doesn’t work on any of those.

I didn’t know Discourse comes with a certificate?  
What would be the difference in using that vs Let’s Encrypt?  
As a starter on everything Discourse, I’m trying to work with what brings less complexity so I don’t get too confused. If Discourse can handle that, awesome. I would still like to understand why pick one over the other, if you don’t mind sharing?

Thanks!
