TL;DR

Investigate and address the AxiosError with status code 401 and connection timeouts to resolve the production issue.

Guidance

1. Verify authentication: Check the authentication credentials and ensure they are valid and properly configured to prevent the 401 status code error.
2. Increase timeout values: Consider increasing the timeout values (e.g., 5000ms, 10000ms) to allow for more time to establish connections and export events.
3. Check server availability: Ensure the server is available and responsive to prevent ECONNREFUSED errors.
4. Review event logging configuration: Examine the event logging configuration to identify potential issues causing events to fail export.

Example

No code snippet is provided due to the lack of specific implementation details in the issue.

Notes

The provided issue content is truncated, which may limit the ability to provide a comprehensive solution. Further investigation into the specific errors and system configuration is necessary to determine the root cause.

Recommendation

Apply a workaround by increasing timeout values and verifying authentication credentials to mitigate the issue temporarily. A more permanent solution will require additional investigation and potentially updating the event logging configuration or server settings.
