I can not log into my digitalocean ubuntu server
I configured my digitalocean ubuntu server from MacOS catalina. At that time I used SSH key authentication and disabled password authentication feature.I was able to access to the server by typing ssh username@ip. Then I have upgraded my system to MacOS Big Sur. And now I can’t login to the server either using ssh root@ip or ssh username@ip.It shows the same error in both cases (** Permission denied (publickey).**) Now, what should I do? Please, help someone.
