NVIDIA Omniverse GPU-Optimized AMI Query

After starting the EC2 instance for the NVIDIA Omniverse GPU-Optimized AMI, the SSH terminals on my Linux local machine where I run my code, suddenly freeze for a while and return intermittently. I am not sure what the issue is and if its related to some instance configuration. I have attached the log from my usage of the instance today where the same issue occurred. Would greatly appreciate your help on resolving this issue. Thank you.
