Public IP not reachable (remote ping)

0

I created a linux instance "Deep Learning OSS Nvidia Driver AMI GPU PyTorch 2.1.0 (Ubuntu 20.04) 20240228" and a flexible IP. I associated it with the VM but if I ping the public address remotely, it writes "connection refused". The firewall rules are the default (listen to all ports). I've launched a jupyter server in the background, it's listening. I don't understand what doesn't work.

Sorry for the delay. This problem was solved immediately by deleting the virtual machine. By mistake I had created an OS linux aws with pytorch nvidia pre-installed on a micro instance. So I think the admin had blocked me.

I initially created groups for the virtual machine. Then I assigned the standard group. I deleted the old groups. Maybe something went wrong. Now I see that the VM has been deleted, and so has the associated flexible IP. I'll try again but I won't use public IPs. Thank you

    Ensure you are in the correct region, as the EC2 wouldn't be deleted without your knowledge. Releasing an Elastic IP is also a manual process.

    If the new EC2 is provisioned without a public IP then it won't be accessible from outside the VPC, unless something like VPN or Direct Connect is in place.

Is there a security group associated with the EC2 instance that allows inbound ICMP ? https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/security-group-rules-reference.html#sg-rules-ping
