Problems trying to convert a .iso to .ova file

I have a .iso image from which I want to create a .ova , But everytime I run into a problem

Error: Curl error: Couldn't connect to server

Completed with errors

Here is the command I used,

ovftool vi://user:master/@14.23.12.34:443/rt4/www/html/imgs/qweTER7.3/.tyRani/NEWCFT/CFT-NEW-5.23.23.iso /rt4/www/html/tmp_ova/CFT-NEW-5.23.23.ova

Not sure whats wrong with this command, I don't have special character in my password or username

please note that 14.23.12.34 is a linux machine and both source and target are in same machine and Im executing ovftool command in same linux machine.

Thank you
