Background of the issue:
I am working on a development site with IP restrictions at hidden link. I need WPML to connect to its server to check for new releases and security updates.

Symptoms:
WPML plugin cannot connect to wpml.org due to network or security settings.

Questions:
How can I allow outgoing communication to wpml.org to remove the connection issue? Is there something I can add or an IP block I can include assuming the reason the plugins are not updating is due to IP/Country Restrictions?

4. Then please click the Register WPML link.
5. Click the Get a key for this site link.
6. It will generate the Key for your site.
7. Copy the key, and paste it back into the input box, and press the Register button.

I did not create a new key. I unregistered the site key in wordpress and then registered the same site key and then it started working again
