Failed to fetch metadata server (404)

When I SSH to my VM, I see a big red error:
```
#########################[ Error ]#########################
# The startup agent encountered errors. Your container #
# was not started. To inspect the agent's logs use #
# 'sudo journalctl -u konlet-startup' command. #
###########################################################
```

Logs:
