Ok, I think the problem is euca tools does not support paths. I have
already tested the following configuration and it works:

:ssl_server: https://devel.cloud.opennebula.org/

$ euca-describe-instances -U https://devel.cloud.opennebula.org  | wc -l
151

$ econe-describe-instances -U https://devel.cloud.opennebula.org/  | wc -l
151


If you use euca with this url; https://devel.cloud.opennebula.org/ you
will get the previous error/timeout. Also if you use econe with this
url; https://devel.cloud.opennebula.org it will return a path empty
error. I will update the econe tools to set '/' by default

Cheers
