Hello Nicolas,
First sorry for the delay!
I checked and your hosting provider is OVH, right ? There’s a known issue with OVH where some servers are blocked by him. And that’s the case, your server is blocking the connection with our server to check the license code.
In this case we will need do a inspection directly from your website and try to activate the license manually. Thus I request sharing your website’s temporary admin login link and send it privately to me over email. You can generate the link with this plugin .

OBS: You are not the first with this issue, and the reason is the OVH hosting.
We await the access to proceed with this thread.
Thanks for your patience.
Kind Regards,
Rodrigo.
