    } catch (e: Ec2Exception) {
        println("Error describing EC2 instances: ${e.message}")
    } catch (e: Exception) {
        println("Unexpected error: ${e.message}")
    }


}

This is wht i did and i am getting an Exception
I have given internet permissions and all so I checked them is this way correct as I am using the credentials directly.
