We are unable to connect with our google cloud Linux VM instance, Suddenly started receiving the below error. It is happening since last week.

1. We tried to launch the new instance using by creating an image but that instance also had the same issue.
2. We increase the disk space, rebooted the instance, and try login in again, but still could not work.

Please suggest how can we solve it and get login into our instance.

More information is required to understand the issue, please contact our support team and file a case with them, they have access to review your logs, and they can review your project for any changes that could affect the connection with your VM. 

And for the message “please consider adding the iap-secured tunnel user iam role….” please refer to this document. 

IAP TCP forwarding allows you to establish an encrypted tunnel over which you can forward SSH, RDP, and other traffic to VM instances. IAP TCP forwarding also provides you fine-grained control over which users are allowed to establish tunnels and which VM instances users are allowed to connect to.
