Agreed, you are looking for a general solution but I lack for now.

Regarding bug #3429299, I noticed another problem.

when server replies with

150 Opening data channel for file transfer.
425 Can't open data connection.

Most of the time, curl is disposing message 425. I have not debug it yet so
do not have an idea who eats the message.

Any idea to help me debug this one?

Thanks.
