JDBC requests fails in docker container

Greetings all !

I have encountered the following problem. At the time of launching the tests through the docker container. All JDBC request steps fail.

My docker image is built from the latest version smartbear / soapuios-testrunner: latest

The database I am trying to connect to is PostgreSQL, so of course I install the database on the image and the JDBC driver dedicated to this database.

Unfortunately, in this statement it does not work, is there anything else I should do?

The important information is that I need to connect to the VPN to be able to connect to the database.

Please help
