Cannot access the host to connect a database via SSH tunneling while getting "Permission denied (publickey)."
After running docker and creating an own PostgreSql database in a droplet, I can access the host via “ssh email@example.com” but I cant connect to the database via SSH tunneling. Here is the command and its response:
root@ubuntu-database:~# ssh -L 5432:localhost:5432 -N -f -l root XX.XX.XX.XX Permission denied (publickey).
I'be assigned the droplet with SSH security rather than using one-time email. Currently, I really have no idea of what is the cause of the problem -whether it’s from the droplet configuration, docker, PostgreSql setting, or SSH usage. I’m an amateur and quite new for this matter. Please kindly help.
Thank you very much.
