This thread is resolved. Here is a description of the problem and solution.
Problem:
You are experiencing an issue where the WPML plugin cannot connect to wpml.org, which is necessary for checking new releases and security updates. This problem usually occurs when the site URL and the registered site URL differ, for example, with or without 'www'.
Solution:
1. Log in to your WPML.org account and navigate to the Sites page: https://wpml.org/account/sites/
2. Delete the existing site key.
3. Log in to your WordPress site, go to Dashboard >> Plugins >> Add new plugin >> Commercial tab and click the Unregister WPML from this site link if it exists.
4. Click the Register WPML link.
5. Click the Get a key for this site link, generate the key, copy it, and paste it back into the input box, then press the Register button.
6. Take a backup of your site and update WPML plugins to the latest version.
7. If the issue persists, go to WP Dashboard Menu >> Updates and press the "Check again" link.
8. If none of the above steps resolve the issue, please provide a debug report in the Debug Information box. You can find how to add the debug report here: https://wpml.org/faq/provide-debug-information-faster-support/
