Get-instance-access for Linux gamelift instance timed out

I cant seem to get access to my linux gamelift instance, when I call gamelift get-instance-access from aws CLI using fleetid and instance id, i am getting timed out. This is a different experience when i do this in a windows gamelist instance.

error is An error occurred (InternalServiceException) when calling the GetInstanceAccess operation (reached max retries: 2): Timeout waiting for reply

Why? This is a freshly created instance, deployed a build, created a fleet, and nothing special done. following tutorials and documentations on how to access an instance fleet, everything is correct and followed on the dot, but cannot get the instance access in CLI because of the timing issue i described above.. This is getting frustrating
