Run Codeception acceptance tests against a self-signed ssl site - selenium

Question

I have a website with a letsencrypt ssl cert. When I ran codeception acceptance tests against it, the test stalls until I press ctrl+z. When I ran the same test against a non ssl site, there is no problem.
That is my setup in acceptance.suite.yml. The phantomjs.cli.args paramater is from this site: http://szdredd.blogspot.de/2013/10/codeception-phantomjs-setup-for.html
class_name: AcceptanceTester
modules:
enabled: [WebDriver]
config:
WebDriver:
url: https://www.domain.de/
browser: phantomjs
My selenium log looks like this:
17:07:15.681 INFO - Executing: [new session: Capabilities [{browserName=phantomjs}]])
17:07:15.682 INFO - Creating a new session for Capabilities [{browserName=phantomjs}]

I found an advise on this side, but when I add that configuration I an error:
capabilities:
phantomjs.cli.args: ['--ignore-ssl-errors=true']
Caused by: org.openqa.selenium.WebDriverException: The best matching driver provider org.openqa.selenium.htmlunit.HtmlUnitDriver can't create a new driver instance for Capabilities [{phantomjs.cli.args=[--ignore-ssl-errors=true], browserName=phantom}]
Who knows how to setup codeception to ignore ssl errors? Any help appreciated!
Thanks

For testing my site I use Phantoman to automatically run and close phantomJS. In codeception.yml I have:
config:
Codeception\Extension\Phantoman:
path: 'vendor/bin/phantomjs'
port: 4444
debug: true
ignoreSslErrors: true
sslProtocol: any
Codeception\Extension\Recorder:
delete_successful: true
