I'm using MySQL Workbench 6.3 to tunnel through an SSH server to connect through a MySQL server. I'm doing this on a MacBook. I recently updated the domain name to which I'm connecting and am now getting this error:
Cannot Connect to Database Server Your connection attempt failed for user '...' from your host to server at mysqlserver.com:3306: Cannot open SSH Tunnel: Error connecting SSH tunnel: The host sshserver.com fingerprints mismatch. Expected key: ... Server sent: ... Please verify if it's correct. To continue, delete entries for the host from the ~/.ssh/known_hosts file file.
The fact that it says "file file" is a little wonky but, anyway, I deleted ~/.ssh/known_hosts file (aka /home/myusername/.ssh/known_hosts) and I'm still getting that error.
https://dev.mysql.com/doc/workbench/en/wb-mysql-connections-methods-ssh.html makes the same recommendation.
Maybe I should just uninstall MySQL Workbench and reinstall it?
