I was using opera 12.10 to launch dragonfly for my work.
Since two/three weeks, i have a fatal error 40 when trying to launch dragonfly.

Is this normal ? Is there a solution to make it work again ?

I have this :

"Unable to complete secure transaction

You tried to access the address https://dragonfly.opera.com/app/, which is currently unavailable. Please make sure that the web address (URL) is correctly spelled and punctuated, then try reloading the page.

Secure connection: fatal error (40) from server."

Thank you.
