I previously followed this guide to add SSH keys to my remote server(I didn't hide or remove the keys from anywhere, just to be sure I don't lose access). It was passphrase protected. However I changed the passphrase to something else, and changed it back to the old one but now I can't login to it using another terminal session. Only my current terminal session is logged on, and unfortunately this is all as the root user. I generated new SSH key and added it to the server as well as my machine too but I still can't logon on it from another terminal session. How can I fix this?!
I fear I'd get locked out if I can't find a solution in time, that is, if my internet disconnects..
