[Resolved] Split: can not connect to WPML.org

Problem:
The client was experiencing issues with their WPML plugin after switching hosting providers. The plugin was not connecting properly, and they were receiving a cURL error 28. The hosting provider's investigation suggested that the plugin might need to be reconfigured due to the hosting switch.

Solution:
1. We advised the client to unregister their site from WPML and then register it again.
- Unregister: https://wpml.org/faq/install-wpml/#unregister
- Register: https://wpml.org/faq/install-wpml/#register
2. We instructed the client to check the Installer Log under WPML > Support to ensure the subscription was working correctly.
3. We asked the client to go to Plugins -> Add New -> Commercial and click 'Check for Updates' to see if any messages appeared.
4. We identified that WPML might be blocked by a firewall and recommended contacting the hosting provider to whitelist certain domains:

• wpml.org
• cdn.wpml.org
• api.wpml.org
• api.toolset.com
• cloudfront.net

5. We performed tests on a staging site and confirmed that the Automatic Translation Editor (ATE) was connected without errors and that WPML registration was possible. We suggested that the server might need to have the IP addresses of our domains manually added to the /etc/hosts file due to DNS resolution issues.
