Connect to a Virtual Machine via the Gcore customer portal

The VNC console in the Gcore Customer Portal provides browser-based access to a Virtual Machine (VM) without requiring internet access on the VM — useful for troubleshooting connectivity issues. Both Windows and Linux VMs are supported. Connecting to a Linux Virtual Machine via the Customer Portal requires a password set during VM creation. Without one, use SSH keys instead.

On Windows VMs, the password is set in the Access field during VM creation — the User data field cannot be used for passwords on Windows. Enter that password at the login screen.

To connect to a Virtual Machine:1. In the Customer Portal, navigate to Cloud > Virtual Instances.2. Find the VM to access and click its name to open it.

The VM connection is established.

Linux VMs without a configured password cannot connect via the Customer Portal — use SSH keys instead.

For VMs in a private subnet only, the Dynamic Host Configuration Protocol must be enabled in the subnet settings for password-based login to work.

To connect to a Virtual Machine:1. In the Customer Portal, navigate to Cloud > Virtual Instances.2. Find the VM to access and click its name to open it.

3. Next to the VM’s IP address, select the Access to Console link. The VNC console will open.

4. Log in using the following credentials:

username : Shown next to the Access to Console button in the format [username]@[ip-address] — typically the OS name, for example ubuntu. The VNC terminal displays this as login:.
password : The password set in the User data field under Additional options during instance creation.

If a password was set during VM creation but is no longer known: connect to the VM via SSH and run sudo cat /var/lib/cloud/instance/user-data.txt. The password appears in the line: password: [password]. If a hash was used, the hash appears instead of a readable value.

The Virtual Machine connection is established.
