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?

[תמונה] auryn_macmillan: I’m running Ubuntu 16.04 I only really work with RHEL distros, but you can try this command to see if there’s a firewall running: sudo ufw status verbose If it’s running, this command will disable it: sudo ufw disable

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

[תמונה] I’ll try a rebuild on CentOS later tonight and will let you guys know how I go.

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.

[תמונה] auryn_macmillan: which: no docker.io in (/sbin:/bin:/usr/sbin:/usr/bin) I get this error, too. It’s not a problem because the launcher locates the Docker binary elsewhere.

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.

Incoming rules: [תמונה] Outgoing rules: [תמונה] Confirmation that the EC2 is using this security group: [תמונה]

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.
