Hi TUSHAR BOHRA
The message AWS Authentication Connector: MxLogger initialized is generated internally by the AWS Authentication Connector module itself specifically during its initialization lifecycle. This typically fires when The Mendix runtime starts up, and At scheduled intervals (notice the ~1 hour gap between your two log entries this strongly suggests a scheduled event or token refresh cycle within the connector is re-initializing the logger).You cannot remove this log message directly since it's baked into the connector module's Java code.
But you can supress this by Going to your Mendix Cloud / Developer Portal → Environments → your environment → Log Levels, and set the log node AWS Authentication Connector to WARNING or higher. This will suppress INFO-level messages from that module without affecting your app's other logging.
I hope this helps!!
