I stopped the instance in GCM and rerun it again but I got this error:
Could anyone help?
According to Google Cloud FAQ:
Error Code 4003
This might mean the instance isn't listening on the port you're trying to connect to or the firewall is closed. Either of those issues could also cause the start-up connectivity test to the VM instance to fail.
As suggested, you should try connecting without Cloud Identity-Aware Proxy.
Check if your firewall rules allow SSH connection, you should look for default-allow-ssh
If the firewall and IAP do not resolve your issue, you can follow this guide: Troubleshooting SSH
I had the same problem couple of times, but they resolved themselves after couple of minutes.

I am unable to ssh into a VM on GCP Compute Engine
However, when I run the command with the --troubleshoot flag, it seems like everything is okay.
When I connect through the console, I get an error message saying "You cannot connect to the VM instance because of an unexpected error".
Also, other people from my organization are able to connect.
I am unable to figure out what the error is. Any help would be appreciated.
From the error message that you got "Permission denied (publickey)" you can check this documentation for further troubleshooting.
Further more you can investigate also the Identity-Aware Proxy (IAP).
If you use Identity-Aware Proxy (IAP) for TCP forwarding, update your custom firewall rule to accept traffic from IAP, then check your IAM permissions.
Update your custom firewall rule to allow traffic from 35.235.240.0/20, the IP address range that IAP uses for TCP forwarding. For more information, see Create a firewall rule.
Grant permissions to use IAP TCP forwarding, if you haven't already done so.
For the error message "You cannot connect to the VM instance because of an unexpected error".
The VM is booting up and sshd is not running yet. You can't connect to a VM before it is running.
To resolve this issue, wait until the VM has finished booting and try to connect again.
The firewall rule allowing SSH is missing or misconfigured. By default, Compute Engine VMs allow SSH access on port 22. If the default-allow-ssh rule is missing or misconfigured, you won't be able to connect to VMs.
To resolve this issue, Check your firewall rules and re-add or reconfigure default-allow-ssh.
sshd is running on a custom port. If you configured sshd to run on a port other than port 22, you won't be able to connect to your VM.
To resolve this issue, create a custom firewall rule allowing tcp traffic on the port that your sshd is running on using the following command:
gcloud compute firewall-rules create FIREWALL_NAME \
--allow tcp:PORT_NUMBER
For further troubleshooting on SSH you see this documentation on Common SSH errors.
it seems I've run though everything and it will not connect,
I've verified my firewall is not blocking anything, I reset my ssh keys, I've set my user roles, and I've tried resolving it through the cloud shell.
Code: 4003
Reason: failed to connect to backend
You may be able to connect without using the Cloud Identity-Aware Proxy.
Anyone have any ideas? I just need this to work.
vm instance- OpenLiteSpeed Wordpress
zone- us-east4-b
machine type- n1-standard-1
cpu platform- Intel Broadwell
It seems you already tried to troubleshoot issue , I had similar issue so just want to know below
what is your role in project ( owner/editor)?
VM instance having external ip or not?
If firewall blocking it will give timeout error, its not timeout error.
Unable to connect to Google Cloud VM via SSH.
I have faced the below-mentioned error while trying to connect VM.
So far I have tried following things,
Code: 4010 - Connection via Cloud Identity-Aware Proxy Failed
Google VM instance Connection via Cloud Identity-Aware Proxy Failed (code 4010)
Could you please tell me anyone is this issue is related to any SSH key. I thought ssh key has been expired. So, I have generate new SSH private & public key via PUTTY Gen
Then I have update public key in Google cloud->Metadata->SSH Keys -> Edit
Followed many documents to generate ssh key & add ssh key
I am unable to add ssh key in Instance-> Edit-> SSH key facing below mentioned error.
Need to start tomcat service imediately last 12 hours service has been stopped due to this issue. Could you please suggest any way to start atleast apache tomcat service?. Please let me know if need any clarification.
Could you please help me anyone to resolve this issue.
Don't mark as duplicate question. It's related to someother issue. I have already checked existing forums. Not working.
How should we know the SSH key is expired?
<protocol> <key-blob> google-ssh {"userName":"<username#example.com>","expireOn":"<date>"}
You can check out expireOn.
The common solution is the firewall. Please check your firewall is configured correctly and open on the port you're connecting to. You can use Connectivity Tests to identify any connectivity issues.
Also, you should be able to see the instance's serial console output using the GCP console - go to the instance's details and click on Serial port 1 (console) and you will see the output.
GCP has provided the documentation of troubleshooting.
The second issue shows that you're facing some IP problems, so I still suggest that review any network service that you using.
I made an instance and connected SSH in my project. My project is for machine learning, so I opened jupyter notebook and ran it. But the terminal always sends me an error like this.
"Connection via Cloud Identity-Aware Proxy Failed
Code: 1006
Please ensure you can make a proper https connection to the IAP for TCP hostname:https://tunnel.cloudproxy.app.
You may be able to connect without using the Cloud Identity-Aware Proxy."
I have tried to create firewall rule but this doesn't work.
Someone says that this is because of session timeout. If it is, what can I do to solve it?
I am following the code labs https://www.spinnaker.io/guides/tutorials/codelabs/gce-source-to-prod/ but I am facing a problem in creating server group in STEP-1. (Deploy stage). The page is getting loaded for infinite time. I think I can say It is not going beyond that point. I am able to come up to this step only if I am using AZURE or any other local machines. If I use Google Cloud Instance to do SSH tunneling I am not even able to create a application. Can you please help me.
You might need to do some additional troubleshooting to determine where the problem is. For example, run netstat on the machine to see whether it's listening on port 9000. See if you can create a firewall rule allowing inbound traffic on that port and then try to connect directly without using the SSH tunnel.
