Unable to connect with VM with browser SSH

[rohithkp]

Hi  , I am unable to connect with my Virtual Machine via browser ssh after upgrading to custom-1-2816.

troubleshooting tool gives no error.

Don't have any idea how to debug further.

Thanks in advance

Have there been any changes to firewall rules recently?

In both cases it indicates it is using IAP, do you have the right firewall rule for IAP? see: https://cloud.google.com/iap/docs/using-tcp-forwarding#create-firewall-rule

I have not changed any rules.

When trying to connect from from local system via ssh and google cloud shell, i got the exception

' Permission denied (publickey). 
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255].'
For other instances, I don't face any issues while connecting with browser ssh / Google shell  ssh.

Do you have your SSH key on your local system configured for access?

Yes, I configured it to debug the issue. 

Note : I configured the project wide SSH key for debugging.
