Hi Adrian, this bug should go upstream.  I'd reopen 1329 and cite your gentoo bug.

[Comment 2 Sandu Adrian 2014-01-30 21:15:54 UTC]

Hi,

Bug 1329 is still open .. waiting for some kind of activity for the past day or so .. Maybe other devels here will make a patch or something :-s

Thanks.

Okay let's wait and see.  We need to proceed with stabilization of 35 for security reasons, bug #499902.  Since this is present in 34 and 35 its not a regression and should not block.

[Comment 4 Sandu Adrian 2014-02-05 10:13:08 UTC]

Hi again,

So it seems .. curl changed its default behaviour about some ciphers .. As in .. it doesn't like the insecure ones now by default without us knowing .. 

There also seems to be a problem with IIS 7.5 and TLS negotiations .. 

More details on the bug pages ..  Will see how they develop a more nicer way of telling the user to try other ciphers/ssl options .. etc.

Thanks ! Everything works now.
