The authenticity of host can't be established - Not new machine or SSH key
Hi folks, I am getting a “The authenticity of host can’t be established” error when I try to ssh into my droplet. I'be searched and found answers saying that this is standard for NEW machines, but I have been logging into this droplet, at this ip address, from this same desktop, using this ssh key, for several months. So I’m curious what this means that this is happening now, whether I should be concerned about security here, and what I should do to get connected again.
To my knowledge, I haven’t made any changes to the droplet or to my ssh setup in between this change occurring.
Here is the exact output, anonymised slightly.
The authenticity of host 'my_ip_address (my_ip_address)' can't be established. ECDSA key fingerprint is SHA256:string_of_letters_and_numbers. Are you sure you want to continue connecting (yes/no/[fingerprint])?
