This thread is resolved. Here is a description of the problem and solution.
Problem:
If you're trying to activate the WPML plugin license or perform updates and encounter an error message stating 'Your site can't communicate with https://api.wpml.org/. Code 403.', this indicates a communication issue between your site and the WPML API.
Solution:
We recommend checking your server's configuration to ensure it allows outgoing connections to https://api.wpml.org/. If the issue persists, it might be due to your site being temporarily blocked by our systems. In such cases, we will need to unblock your site from our end. Please contact us directly so we can assist you further.
Keep in mind that this solution might be outdated or not applicable to your specific case. 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.
