No problem, should have explained myself better.
Not having ssh access to my wordpress host makes everything more complicated. The only thing I could come up with for this issue is this thread at stackexchange; http://unix.stackexchange.com/questions/192944/how-to-fix-curl-sslv3-alert-handshake-failure
It might not be related, but people here could solve the problem updating cURL, in my case I thought I had the last version but I was wrong. Besides this, I don’t have idea on what could be failing.
