Unable to connect to oracle linux(ubuntu) instance with putty (connected recently). pretty sure that my private key is correct.
Error I am receiving : no supported authentication methods available (server sent publickey)
port 22 is open. Putty is updated.
what could be the issue? what could I mess up?
Currently I lost all control over the VM. only way to interact with it is Oracle cloud shell, but it is useless, almost has no permissions.
Please help, I am going crazy...
