Prerequisites
- • Instance ID and project context
- • Access to security group and network configuration
Fast triage checklist
Most access incidents are caused by security group rules, missing floating IP associations, or incorrect SSH keys.
- Confirm instance is ACTIVE and in the expected project.
- Verify floating IP exists and is associated to the correct port.
- Verify security group inbound TCP 22 from your source IP.
- Validate you are using the matching private key file.
Deep checks
If connectivity still fails, inspect route tables, router gateway state, and instance console logs for cloud-init failures.
Verbose SSH for diagnostics (bash)
ssh -vvv -i ~/.ssh/monal-cloud ubuntu@<floating-ip>
