I am trying to connect to MySQL server hosted on google cloud compute server. I believe the issue is not MySQL authentication related, but rather SSH. MySQL workbench seems to be unable to connect on SSH with “Authentication error opening SSH tunnel”.
I am able to open a putty SSH connection to the server using the same IP, user and private key on the same computer.
Connection is configured as:
SSH Hostname: [ip of my google cloud server] SSH Username: [username used in putty ssh] SSH Key File: [same ssh-rsa ppk file I use in putty] MySQL Hostname: 127.0.0.1 MySQL Server Port: 3306 Username: [mysql user that works from putty] Password: [mysql password that works from putty]
