Apache Spark in Azure Synapse Analytics - HTTP request in notebook - pyspark

Question

I use a Notebook in Synapse where I run my Python code.
I would like to make an API request from this Notebook to Microsoft Purview to send the entities.
I added the pyapacheatlas library to spark.
On my local computer, this code works fine in Visual Studio.
I need to sign in with Microsoft. I created Purview client connections using a service principal. Here is the code that I am running:
from pyapacheatlas.auth import ServicePrincipalAuthentication
from pyapacheatlas.core import PurviewClient
from pyapacheatlas.core import AtlasEntity
auth = ServicePrincipalAuthentication(
tenant_id="...",
client_id="...",
client_secret="..."
)
# Create a client to connect to your service.
client = PurviewClient(
account_name = "...",
authentication = auth
)
# Get All Type Defs
all_type_defs = client.get_all_typedefs()
I am getting an error after running for a long time:
"ConnectionError: HTTPSConnectionPool(host='login.microsoftonline.com', port=443): Max retries exceeded with url: /.../oauth2/token (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f00effc5250>: Failed to establish a new connection: [Errno 110] Connection timed out'))"
It turned out that I can't make any HTTP requests in Notebook.
Please advise, maybe this is not provided by the functionality or is it possible to solve it?
Thank you.
Even an ordinary GET like this:
import json
import requests
r = requests.get("http://echo.jsontest.com/insert-key-here/insert-value-here/key/value")
df = sqlContext.createDataFrame([json.loads(line) for line in r.iter_lines()])
As a result I get:ConnectionError:
"HTTPConnectionPool(host='echo.jsontest.com', port=80): Max retries exceeded with url: /insert-key-here/insert-value-here/key/value (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f90b0111940>: Failed to establish a new connection: [Errno 110] Connection timed out'))"
