MySQL Workbench returning SSH tunnel error

Linode Staff

I'm trying to connect to a MySQL database on my Ubuntu 20.04 server using PuTTy. Port 22 is open and listening for SSH, and I can connect normally but using MySQL Workbench to connect returns the error:

Authentication error: unhandled exception caught in tunnel manager, please refer to the logs for details

What could be causing this error and what are my next steps for resolving it?
