Neo4j Graph Platform Aura & Cloud

Hello,

I set up my own AWS instance using the ami-03de3ac0f7ecf9ece AMI. It's a t2.micro in the eu-central-1 region. The machine starts and i can SSH into it.

However, neo4j fails to start. The neo4j logs are empty, but checking /var/log/syslog shows the following

Can someone let me know if they used the same AMI and if it worked for them? Or, alternatively, how to fix this issue?

Thank you,

I'm not seeing this one under our ownership, it might not be ours. Can you confirm the AMI's owner number?

Hi @andrew_bowman,

Thanks for taking a look at my issue!

You can see the AMI here: https://eu-central-1.console.aws.amazon.com/ec2/v2/home?region=eu-central-1#Images:visibility=public-images;imageId=ami-03de3ac0f7ecf9ece;sort=name

The owner is 385155106615, the same one mentioned here: Deploy to Amazon EC2: Host a Single Instance of Neo4j on AWS - Developer Guides

Cheers,
Silviu

Ah, okay I think I see what's going on.

The 4.0 AMIs should not have been made publicly available. These are not in a good state to use right now, they're still being built out, I'm checking if we can disable public exposure for these.

Any ideas when thell become available?

I believe we're aiming for a release within the next week or two.

Thanks, @andrew_bowman! Looking forward to the release.
