Any chance you can try a recent daily snapshot? We did changes to the multi state machine that I suspect might have improved this.

** [bugs:#1474] Cannot open FTPS encrypted data connection through HTTP proxy**
**Status:** pending-needsinfo
**Labels:** SSL ftps proxy 
**Created:** Thu Jan 22, 2015 11:06 AM UTC by Marco De Vitis

When trying to transfer a file via FTPS through a HTTP proxy (Blue Coat ProxySG), curl fails when trying to open the encrypted DATA connection returning the following error:
curl: (35) error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
This surely happens with recent curl versions (7.39 and 7.40), on Red Hat 6.3.
The transfer works fine instead with previous versions, like 7.19.7, 7.25.0, 7.26.0 and 7.27.0.
I attach the log files obtained with the -v option both from 7.40 (not working) and 7.19 (working), from the same Red Hat 6.3 machine over the same proxy.
The logs also contain the output of curl -V and the command line used:
curl -O -v -k --ftp-ssl --disable-epsv --proxy <proxyIP>:3128 --proxytunnel ftp://<ftpUser>:<ftpPassword>@<serverIP>//testpub.xml
Also note that when disabling data channel encryption with the --ftp-ssl-control option then the connection occurs but a different problem happens during the file transfer, see ticket [#1473].
