Question

Server's SSH key fingerprint shown in Putty is different from Droplet setup

Posted August 20, 2020 389 views
Initial Server Setup

I’m testing hosting a forum on a droplet, ran into some trouble, destroyed the droplet and started from scratch. I have an SSH key stored in my Digitalocean account, and when I created the new droplet, I associated it with that SSH key.

Then when I connect to the droplet with Putty for the first time, to the IP-address displayed for the droplet, Putty shows me a different SSH key fingerprint than what I see in Digitalocean.

What’s going on? It’s as if Putty connects to someone else’s droplet?

Hi @lyseoy,

It does seem to me like the new droplet you created had the same IP as your previous droplet.

Basically, if you created the new droplet immediately after destroying the old one it’s really plausible the IP was the same. Now on to why this matters. Your putty client has associated your own fingerprint with this IP address. Now that you have a new droplet, there is a new fingerprint. It’s nothing to worry about, you can just remove the saved information about that fingerprint you have on your local environment.

Regards,
