How to repeat:
Open any other connection even if to another server into the same network.

Hi Mr. Ibanez,

Thank you for your bug report.

However, we do not have sufficient info that would enable us to repeat the behaviour.

First of all, you have chosen a category of "MySQL Server: General", while your report is only describing the Workbench.

Next, can you try whether you have provided the correct IP address to the Workbench. 

In order to find out that, please use MySQL CLI or MySQL Shell and try to connect with it through SSH tunnel.

Also, please, try establishing the SSH tunnel and simply try to ping the address.

Then you will know whether you have established a proper SSH tunnel.

Can't repeat.
