I am facing the following error while getting into Google Cloud Instance using the serial port. When I run this command, it starts throwing the error.
gcloud compute connect-to-serial-port instance-1
This is the error:
Sep 20 14:28:35 instance-1 OSConfigAgent[670]: 2022-09-20T14:28:35.5396Z OSConfigAgent Error main.go:196: network error when requesting metadata, make sure your instance has an active network and can reach the metadata server: Get http://169.254.169.254/computeMetadata/v1/?recursive=true&alt=json&wait_for_change=true&last_etag=b6d33d232458e45a&timeout_sec=60: dial tcp 169.254.169.254:80: connect: network is unreachable

I am also unable to access the instance using external IP, and the SSH does not work either. SSH throws the following error:
These are my network rules.
I don't want to restart my instance as I have a job running in Jenkinwhich will destroy the whole day's runtime.
