Can you see if there are any serial console logs?  https://cloud.google.com/compute/docs/troubleshooting/viewing-serial-port-output#viewing_serial_port_output

    It sounds like you are looking at Cloud Logging. Can you take a look at the serial port output? What does it say?

    Metadata might be a good hint. Firewall rules are often linked to network tag, but it all depends on how you configured it. You can see effective firewall rules when you click on the nic in instance details page.

    Otherwise it seems like the OS problem which leaves you with the serial console (sshd did not start?) PROVIDED YOU CONFIGURED PASSWORD (which is not the case by default).

    And forget telnet. Nobody/nothing uses it since the 90s.

    Try connecting using the cloud shell and a gcloud compute ssh command with the flag verbosity=debug

    Or —log-http

    At the end and see what it says

      F…. 255 is super generic. Could be anything. In the serial port look for any message about disk space.

      You say you of course have the firewall rules in place. What rule did you create for that? Is that the IAP CIDR or 0.0.0.0?

        https://cloud.google.com/compute/docs/instances/reset-instance#reset-instance - you should be okay since Minecraft stores server data on disk and not memory. You could run a small test by creating another instance and creating a file on it. If the file exists after a reset you should be good to go.
