[Resolved] Can't register site key or update plugins

Problem:
The client was unable to add a site key to their website and suspected that their IP might be blocked by the WPML API server, as indicated by an 'X' next to it in the Installer Support.
Solution:
We escalated the issue to our system team, who then unblocked the client's site. We advised the client to delete the existing site key and create a new one by following these steps:
1. Log in to your WPML.org account and go to the Sites page.
2. Delete the existing site key.
3. Log in to your site, navigate to the Dashboard >> Plugins >> Add new > Commercial tab and click the Unregister WPML from this site link.
4. Click the Register WPML link.
5. Click the Get a key for this site link.
6. Generate the key for your site.
7. Copy the key, paste it back into the input box, and press the Register button to see if this resolves your issue.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket.
