Root Cause

Some users were unable to log in because their accounts or IPs were flagged by an overly strict rule that blocked access based on shared IP usage.

Resolution

The restrictive rule was disabled to restore access, resolving the login issue.

Action Plan

The team refined the rule to better align with expected behavior and is monitoring its effectiveness to reduce false positives. They are also improving error handling, organizing a workshop on platform security, and evaluating ways to enhance privacy for specific attack vectors.
