Hi Gabriel, ...
Go to Preferences -> Advance -> Encrypt (or similar, I don't have the english version here). 'View Certificates' -> Servers -> Add Exception
Thanks, found it.
But ...
And fetch the certificate from: https://www.berlios.de/
that must be https://developer.berlios.de/
Hope that helps.
Yes, thank you.
