The SSH host key of my server has changed
Issue Encountered
The SSH host key of your VPS server has changed.
Cause
The SSH key of the host can change for several reasons:
- The key was regenerated by your VPS OS during your own manipulation
- Cloud-Init was re-executed from the client OS during your own manipulation
- The VPS has been reinstalled
- In very rare cases, this can happen when upgrading the VPS from one offer to another.
Solution
If the VPS has undergone one of the operations described above, there's no need to worry. However, if you are not the origin of this change, we encourage you to get in touch with our support so we can check if there has been any action on our part.
If we can't find the origin of this change and you can't either, we strongly recommend following the guide at the following link: https://docs.pulseheberg.com/en/article/your-server-has-been-compromised-9d0uki/ to ensure the VPS is not compromised.
