SSH tunnelling failure between Metabase and Postgresql - postgresql

Question

Trying to add a Postgres database on Metabase via SSH tunneling I ran into an error giving me the following error message: "Server error encountered"
My logs are very similar to #williamjacksn 's logs on the post:
http://discourse.metabase.com/t/ssh-tunnel-failure/2469
I am certain that my credentials are OK since I use the same for a Postico SSH connection as well as a DBeaver connection.
I already checked the following fix: https://github.com/metabase/metabase/pull/6970
Howerver I have no idea how to use it as i cannot find the ssh.clj file on my machine.
Would there be a fix for this ?
Extra info:
Install via the .jar file. Working on Firefox 58.0.2 | Mac OSX 10.10.5
Thanks in advance

Answer 1

I already checked the following fix: https://github.com/metabase/metabase/pull/6970 Howerver I have no idea how to use it as i cannot find the ssh.clj file on my machine.
To try out the ssh.clj changes proposed in the pull request you need to get the source code from GitHub, then build Metabase yourself from source code. I just happen to have described the steps over on the Metabase discussion forum for someone in a similar situation (though needing a different PR for a different purpose):
