[Python] Implementing a Simple Icecast Client using Python

I am learning Python these days for data-science, ML and network programming amongst other things. I am trying to implement a simple Icecast client to stream live audio to Icecast server such as RadioKing and Caster.fm. My code is as here.

import pyaudio
from pydub import AudioSegment
import requests
import base64

FORMAT = pyaudio.paInt16
CHANNELS = 1
SAMPLERATE = 44100
CHUNK = 1024
#
audio = pyaudio.PyAudio()
stream = audio.open(format=FORMAT, channels=CHANNELS,
rate=SAMPLERATE, input=True,
frames_per_buffer=CHUNK)
#
raw_audio_data = stream.read(CHUNK)

audio_segment = AudioSegment(
data=raw_audio_data,
sample_width=audio.get_sample_size(FORMAT),
frame_rate=SAMPLERATE,
channels=CHANNELS
)
encoded_audio_bytes = audio_segment.export(format="ogg").read()

#
ICECAST_HOST = "https://sapircast.caster.fm"
ICECAST_PORT = 15754
MOUNT_POINT = "/iCVJp"
USERNAME = "source"
PASSWORD = "m5auo6W0vP"
#
enc_pw = base64.b64encode(f"{USERNAME}:{PASSWORD}".encode()).decode("iso-8859-1")
plain_pw = f"{USERNAME}:{PASSWORD}"
#
stream_url = f"{ICECAST_HOST}:{ICECAST_PORT}{MOUNT_POINT}"
session = requests.Session()
session.auth = (f"{USERNAME}", f"{PASSWORD}")
ice_headers = {
"User-Agent": "python-requests/2.24.0",
"Accept-Encoding": "gzip, deflate",
"Accept": "*/*",
"Connection": "keep-alive",
"Authorization": f"Basic {enc_pw}",
"Content-Type": "audio/opus",
"icy-pub": "1",
"icy-genre": "*",
"ice-name": "Test",
"ice-description": "Test stream",
"ice-url": f"{ICECAST_HOST}",
"ice-bitrate": "96",
"ice-audio-info": "ice-channels=2;ice-bitrate=96;ice-samplerate=44100;",
}
#
while True:
try:
response = session.put(stream_url, data=encoded_audio_bytes, timeout=120, headers=ice_headers, stream=True)
response.raise_for_status()
except requests.exceptions.RequestException as e:
print(f"Error sending audio to Icecast: {e}")
except requests.exceptions.HTTPError as e:
print(f"Error sending audio to Icecast: {e}")


When I run the programme with Caster.fm server running, the programme fails to make connection. What am I doing wrong? Please, help. A typical output is as below: -
