I am getting this output when running a mount -av on my EC2 instance: I already have the allow incoming in the security group for the IP of EFS and the allow for the IP of the EC2 in the security group attached to the EFS. I don't and can't have DNS configured.

I have also tried this method with no luck:
mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport mount-target-IP:/ ~/efs-mount-point
