This is urgent. Please help me. The support does not seem to be interested in responding.

I have executed chmod 777 on / before I knew what I was doing. After I saw tons of errors like Operation failed:... something... to ~/%name of some root folder% in my console I couldn’t prevent the server from keeping executing the command, so I couldn’t think of anything better than to log into my account and turn the droplet off immediately from the control panel. I did that.

I turned it on again, and I can’t log in via SSH since then. It says: Connection closed by %my_ip% port 22.

Neither can’t I access the server via SFTP; it says Unable to exchange the encryption keys.

I had been logging in with root user, and the only user I have created and remember the password for doesn’t seem to be allowed to execute sudo, so I can’t restart SSH on the server.

I have read online that by executing this command I have crashed my entire filesystem. Could it be restored, at least the part of it where the SSH is? Or, can I backup certain folders just with DO dashboard console logging in as non-root user? Or, how do I log in as a root user from there? Typing root as user does not work.
