When SSH connection to Sakura VPS becomes unavailable, you can log in using the serial console. The serial console functions as an emergency workaround for accessing your VPS even when normal SSH connection over the network is not available.

The method to access the serial console is as follows:

  1. Log in to the Sakura VPS control panel.
  2. Select the target VPS.
  3. Find and click the “Serial Console” option.
  4. Follow the instructions to connect to the serial console.

Using the serial console, you can perform system configuration and repair work even if SSH keys are incorrectly configured or communication is blocked by a firewall. However, proper authentication credentials are required to use the console securely.
