Thank you for your response. I’m using Windows 10 ubuntu bash.
I still cannot gain access to the droplet.
I have also verified that public key in /home/alex/.ssh/id_rsa.pub is registered on digitialocean SSH Keys. Again, it was working a few months ago and I haven’t made any changes.
Here is what I get when trying to ssh
