Description:
After upgrade from WB 6.3.10 to 8.0.11 and 8.0.12
ssh tunnel with key authentication are not established.

Creating a local tunnel 
ssh -L localhost:33060:localhost:3306 user@server
and connecting via WB does work.

I get following error on fresh install and restored connections (working on previous version)

How to repeat:
When using a server with ssh and authentication with key setup, no connection/tunnel can be created

wb log when trying to establish connection with previously working connection configuration

Thank you for the bug report. Which exactly Linux OS are you using?. Thanks.

I'm using Arch Linux default/stable repository even patching following code did not resolve the issue.

Thank you for the feedback. Unlucky currently Arch Linux isn't supported OS.

I would say 

supported through

Generic Linux (tar format).

So please provide any useful hints if you have any.

because I downgraded the WB and now it works as expected.

ED25519 Keys can not establish a ssh tunnel.

Whether Linux nor Mac
