![]() ![]() Official documentation about this Connection failed, code 255. Establish an SSH connection: putty.exe -ssh for status in the serial console logs. Make sure the VM has started up successfully. Make sure that the instance has not run out of memory. Make sure that the root volume is not out of disk space. Open PuTTY Type the name of the server you are connecting to in the Host Name field, check that the Connection type is set to SSH, then select Open If you. Verify that SSH access to the instance is not blocked by a firewall. Mv ~/.ssh/google_compute_engine.pub ~/.ssh/old-google_compute_engine.pub Move the existing key pair aside using these commands:mv ~/.ssh/google_compute_engine ~/.ssh/old-google_compute_engine Try the gcloud again after performing the UI ssh.įorce gcloud to recreate the user's SSH key pair then try gcloud compute ssh again. This approach will address common gcloud compute ssh issues that relates to corrupted keys, missing dir/file or invalid dir/file permission. This creates an ephemeral ssh key, Google Agent also executes the codepath to refresh .ssh/authorized_keys and address any invalid dir/file permissions for both. Make sure that the user has authenticated to gcloud as an IAM user with the compute instance admin role for example, run gcloud auth revoke -all, gcloud auth login then try gcloud compute ssh again. The Google Agent has not yet read the SSH keys metadata. The first step is to configure a Master session that can successfully connect via the SSH protocol to the gateway server (also known as a jump host).Metadata for SSH keys has not finished being propagated to the project or instance.A login as: message will pop up and asks you to enter your SSH username. The instance has not finished starting up, or that the SSH session was terminated. After getting all the SSH connection information, follow the following steps: Launch the PuTTY SSH client, then enter your serverâs SSH IP and SSH Port. ![]() ssh/authorized_keys, authentication, etc), or simply the service is not reachable. Code 255 usually results when SSH intentionally terminates a session and prevent user access due to errors (wrong permission on. TIP: Return Code 255 is perfectly normal if the SSH session was terminated (for example, if you issued sudo reboot now). ![]()
