Hello all,

I will recommend checking our tutorials on How to Connect to your Droplet with PuTTY on Windows and How to Create SSH Keys with PuTTY on Windows

Alright, this is the way I solved it:

1.- Paste your PUBLIC ssh key in and get the raw version of your paste, example: (If you dont remember your public key, simply load your private key into PuTTYgen and copy the content that says “public key for pasting into OpenSSH authorized_keys file”)

2.- Then login to the online console and find your authorized_keys file, it is by default in “~/.ssh/authorized_keys” (the ~ stands for your HOME enviroment variable in my case it is “/root”)

3.- In the folder where is your authorized_keys file execute this command: wget '' -O authorized_keys (remember to replace the raw pastebin link with your own)

Hope it helps
