@Abegail,

Please provide some specifics of your setup and explain exactly what is happening. It is very hard to figure out from such a limited explanation.

This is more likely something to do with your networking setup than your OpenERP/Odoo setup. I'd recommend looking into how your network is setup and how everything in your network connects to your Odoo instance's IP address and port.

@Luke, I solved it by making self-signed certificate .This is more likely router firewall blocking the script.
