Connection to JIRA API using the python library fails with basic authentication. Try this revised example:
from jira import JIRA
# Set your JIRA server URL
server_url = 'https://jira.example.com'
# Initial connection attempt
client_instance = JIRA(server_url)
# Attempt authentication
user_id = 'user123'
user_secret = 'pass123'
auth_client = JIRA(basic_auth=(user_id, user_secret))
In my experience, connection issues with the python-jira library can often be resolved by adjusting how authentication is handled right at the initialization phase. Rather than setting up the client and then working on authentication separately, I found that specifying the basic_auth parameter immediately when creating the JIRA instance makes a significant difference. I also encountered scenarios where a mismatch in the server URL or an outdated library version led to similar errors. Ensuring your configuration details and library version are current saved me a lot of time in troubleshooting such problems.
In my own experience, resolving connection issues with python-jira required verifying that all environmental settings were correct. Problems arose not only from device authentication but also from subtle issues in the server URL such as unnecessary trailing slashes or protocol mismatches, which can be overlooked. It was helpful to test connectivity outside the library to ensure network access and firewall configurations were not interfering. Furthermore, for some instances, updating the library and checking for token-based authentication compatibility when using JIRA Cloud proved particularly effective.
