HTTP 429 when using PAT authorization through python library

I tried to use PAT to access my account and fetch issues, I got HTTP status 429, but I just create the PAT and only asked one request. 

from jira import JIRA

jira_server = "https://xxxxx.com/"
pat_key = "xxxxxxxxxx"

jira = JIRA(server=jira_server, token_auth=pat_key)

try:
user = jira.current_user()
print(f"✓ Authentication successful! Logged in as: {user}")
except Exception as e:
print(f"✗ Authentication failed: {e}")
