--- Comment #4 from Fabian Maurer dark.shadow4@web.de ---
Hi, I've attached a certificate that should show as invalid once you click "details" (can't remember the name).
How would I click on details through wine? Mind elaborating on that, I have no idea what you are doing or how to reproduce it.
You can also try to access https://ssigames.co - it should also throw an error.
I get an "The certificate is issued by an unknown or untrusted publisher" warning. Is that what you mean?
