Hi,

EDIT: After more tests, this issue appears from version 8.2.0 onwards, while 8.1.3 seems to work as expected. Looking at the change log, I can see the following change for version 8.2.0 `Support IMDSv2 for EC2 Discovery #84410 (issue: #80398)`, could a bug have been introduced, or am I missing some configuration?

I am trying to have my cluster running on AWS' ECS with the discovery-ec2 plugin for clustering. After starting Elasticsearch it seems to hang and nothing is happening happening anymore after the `discovery-ec2` plugin is loaded in, logs (at the end of this post) don't seem to provide much help. Following the various configuration files used and logs:

Dockerfile:

```auto
FROM elasticsearch:8.5.3

ENV CLUSTER_NAME default
ENV EC2_INSTANCE_ID undefined

COPY elasticsearch.yml /usr/share/elasticsearch/config/
COPY --chown=elasticsearch:elasticsearch entrypoint.sh /usr/local/bin/new-entrypoint.sh
RUN chmod +x /usr/local/bin/new-entrypoint.sh

RUN echo "y" |bin/elasticsearch-plugin install discovery-ec2

ENTRYPOINT ["/bin/bash", "/usr/local/bin/new-entrypoint.sh"]

```

Docker Entrypoint:

```auto
#!/bin/bash

export EC2_INSTANCE_ID=$(curl --silent http://169.254.169.254/latest/meta-data/instance-id)

if [[! -e "$B64_TLS_CERTIFICATE"]]; then
    echo -n "$B64_TLS_CERTIFICATE" |base64 -d > /usr/share/elasticsearch/config/elastic-certificates.p12
fi

# Resume to base image entrypoint
/bin/tini -s -- /usr/local/bin/docker-entrypoint.sh "$@"

```

> 
> Past version 8.1.3, clustering on AWS cloud with plugin \`discovery-ec2\` results in having the startup freezing right after the \`discovery-ec2\` module is loaded, and IMDS call is made to retrieve the availability zone the instance is running on. The issue happens through my own image (details provided in steps), as well as through the original image with entrypoint overridden, plugin install, and manual start of the app.
