Hello,

I did a Wireshark analyze to compare the behaviour of Chrome vs. Firefox and
cUrl, and Chrome is doing some weird things, like re-sending a "client
hello" after the "server hello done", instead of sending the client key. I
attached the wireshark files, may be it can help you determine if the
problem is Chrome and not GNUtls?

Best regards,
