Working Elementor Pro offline

Hello. I have a problem. I’m using Elementor Pro on a corporate website that doesn’t have external access. That is, the site only works on the local network. This is the company’s security policy.
Now the plugin with closed access to the Internet does not work for me. This is expressed in the fact that when you try to select “Edit in Elementor” for any page, the editor loading status is constantly displayed. When I open internet access the edit page loads successfully. In this case, the license status is Active. This didn’t seem to happen before.
How can I get the plugin back to work offline?
If necessary, I can send you an email and an Elementor account key.
