whatever, I just made a new key and it seems fine

Hello, @skeddtemp

If you ever face the issue again you can quickly use the console in your DigitalOcean account and access your droplet and check if the ssh-key is present on your droplet.

You can make sure that the key is added in:

 ~/.ssh/authorized_keys

If the key is not there you can try adding it via the console or temporary enable the PasswordAuthentication and ssh to the droplet via password and copy the key using this command:

cat ~/.ssh/id_rsa.pub | \
ssh username@IPaddress "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

Note: Please change IPaddress with the actual IP address of your droplet.

Hope that this helps!
Regards,
Alex
