Failed to establish a new connection: [Errno 110] Connection timed out | Tableau

Question

I'm trying to use Python to build a Hyper extract from a csv and publish it to my Tableau Server using the following code:

!pip install --upgrade tableau-api-lib
!pip install --upgrade tableauhyperapi
!pip install --upgrade panda

import pandas as pd

from tableau_api_lib import TableauServerConnection
from tableau_api_lib.utils.querying import get_projects_dataframe

from tableauhyperapi import HyperProcess, Connection, TableDefinition, SqlType, Telemetry, Inserter, CreateMode, TableName
from tableauhyperapi import escape_string_literal


TS_CONFIG = {
        'my_env': {
                'server': 'my_server',
                'api_version': '3.11',
                'username': 'my_username',
                'password': 'my_password',
                'site_name': 'my_site',
                'site_url': 'my_url'
        }
}

conn = TableauServerConnection(config_json=TS_CONFIG, env='my_env')
conn.sign_in()

However it yields the following error:

ConnectionError: HTTPSConnectionPool(host='myhost', port=443): Max retries exceeded with url: //api/3.11/serverinfo (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7fdaafa0c910>: Failed to establish a new connection: [Errno 110] Connection timed out'))

I'm aware of how the error occurs but I'm quite unsure of how to resolve or debug the error on Tableau. I have been following this article for the task.
