google cloud platform – Can not ping compute engine VM

In the compute engine page GCP prompted me to save $12/month by reducing the size of my VM. After selecting this option and reducing the size of my VM, I am unable to ping the external ip of the VM from external addresses. Also no web traffic. traceroute ends, does not reach the server…

Firewall rules are correct and in place to allow icmp/https/http. Also when I test various networking scenario from the compute engine is says they should work and should pass firewall rules (Ie, it says a ping from my home pc should work, but it does not)…. I am able to ping/traceroute to external ip addresses from the compute engine VM.

I’ve tried several reboots.

Any suggestions welcome. Thanks,
