I’m trying to migrate an instance of Discourse form Digital Ocean over to an AWS EC2. The installation of the new instance seems to work without a hitch, however the EC2 discourse instance seems to be unreachable from my browser. Any idea what this could be causing this and what a fix might be?

I’m open to trying a different distro, I’ve been wanting an excuse to play with some others anyway.

sudo ufw status verbose Status: inactive

Can you post a screenshot of your security group rules? If you do rebuild, I recommend CentOS over Amazon Linux since Amazon Linux cannot be run outside of AWS if you ever need to migrate the instance. AWS Marketplace

Alright, so I just went through the install process on a fresh CentOS 7 EC2. Everything seems to have gone smoothly, although I do notice a something weird: $ ./launcher start app which: no docker.io in (/sbin:/bin:/usr/sbin:/usr/bin) 6dd44a3a02af Nothing to do, your container has already started! Anyway, this instance seems to be suffering the same problem. So I’m guessing this means it must be something to do with my security group settings. Although as far as I can tell, they are all as they should be.

Although as far as I can tell, they are all as they should be. Was the screenshot you posted of incoming or outgoing rules? Can you screenshot both for me? And just confirm that the EC2 instance is actually using that security group.

Bizarre. And you can still SSH in, but not connect on any port besides 22? If you want, you can PM me the credentials for a temporary account and I can log in to have a quick look around. I don’t mind if you can do it before I leave for a New Year’s party. :slight_smile: Otherwise, you can open a ticket with Amazon and they should be able to fix it in a day or so.

Yeah it’s really bizarre. Will DM you.
