How to connect unleash to server what does parameters mean?

[Era-cell]

Hey frontend is good,
but in server side sdk im very confused: I have used python SDK
my code:
client = UnleashClient(
url="http://localhost:4242/api",
app_name='V11',
custom_headers={'Authorization': '*:development.76998a8514449e1b9b83b8ed631c7a9620489f189db0c54b05ff47c3'})

client.initialize_client()

Unleash Client feature fetch failed due to unexpected HTTP status code.
Unleash Client feature fetch failed due to exception: Unleash Client feature fetch failed!
Traceback (most recent call last):
File "C:\Users\supri\AppData\Local\Programs\Python\Python311\Lib\site-packages\UnleashClient\api\features.py", line 74, in get_feature_toggles
raise Exception(
Exception: Unleash Client feature fetch failed!

I am very confused, what is this app-name??? and what is the url ? url of backend server or unleash server and why nothing works
