Google Compute Engine is not responding

Question

My GCP server is down. It was working last day. I can see the server in VM Instances but can not connect using SSH. All the client websites are down.

Can any one help ?

Answer 1

There is several reasons this could happen:

• If your disk is full
• sshd deamon isn't configured properly
• If OS login is enabled on your instance
• A firewall rule block port 20

Sometimes, you see some connection errors in the console, that worth to take a look.

EDIT:

I will need additional information if that still not working;

1. Take a look to your serial console logs and tell me if you have any relevant logs that can help like a kernel panic, issue with networking, permission denied, etc

2. Use Cloud Shell and try to connect to your VM instance with these commands:

   • gcloud compute firewall-rules create --network=default default-allow-ssh --allow tcp:22
   • gcloud compute ssh YOUR_INSTANCE_NAME --zone YOUR_ZONE -- -vvv

If you can't connect from cloud shell, try to ping your VM instance (internal IP & external IP)

3. I highly recommend to delete your screenshots showing information about your VM instance (Firewall rules, Project name, nmap scans, etc).
