Nodes Cant Communicate to eachother

Could you please review the configurations I've provided for both machines? I'm encountering an issue where I'm unable to establish communication between the two nodes in Elasticsearch.
Machine 1

======================== Elasticsearch Configuration =========================

NOTE: Elasticsearch comes with reasonable defaults for most settings.

Before you set out to tweak and tune the configuration, make sure you

understand what are you trying to accomplish and the consequences.

The primary way of configuring a node is via this file. This template lists

the most important settings you may want to configure for a production cluster.

Please consult the documentation for further information on configuration options:

Elasticsearch Guide | Elastic

---------------------------------- Cluster -----------------------------------

Use a descriptive name for your cluster:

cluster.name: my-application

------------------------------------ Node ------------------------------------

Use a descriptive name for the node:

node.name: node-1

node.master: true

Add custom attributes to the node:

#node.attr.rack: r1

----------------------------------- Paths ------------------------------------

Path to directory where to store the data (separate multiple locations by comma):

#path.data: /path/to/data

Path to log files:

#path.logs: /path/to/logs

----------------------------------- Memory -----------------------------------

Lock the memory on startup:

#bootstrap.memory_lock: true

Make sure that the heap size is set to about half the memory available

on the system and that the owner of the process is allowed to use this

limit.

Elasticsearch performs poorly when the system is swapping the memory.

---------------------------------- Network -----------------------------------

By default Elasticsearch is only accessible on localhost. Set a different

address here to expose this node on the network:

network.host: MAchine 1 ip

By default Elasticsearch listens for HTTP traffic on the first free port it

finds starting at 9200. Set a specific HTTP port here:

http.port: 9200

transport.port: 9300

transport.host: 0.0.0.0

For more information, consult the network module documentation.

--------------------------------- Discovery ----------------------------------

Pass an initial list of hosts to perform discovery when this node is started:

The default list of hosts is ["Machine1 ip", "[::1]"]

discovery.seed_hosts: ["Machine1 ip", "Machine2 ip"]

Bootstrap the cluster using an initial set of master-eligible nodes:

For more information, consult the discovery and cluster formation module documentation.

---------------------------------- Various -----------------------------------

Require explicit names when deleting indices:

#action.destructive_requires_name: true

---------------------------------- Security ----------------------------------

*** WARNING ***

Elasticsearch security features are not enabled by default.

These features are free, but require configuration changes to enable them.

This means that users don’t have to provide credentials and can get full access

to the cluster. Network connections are also not encrypted.

To protect your data, we strongly encourage you to enable the Elasticsearch security features.
