[SOLVED] License check timeout

[fabricators]

Hello,

I just purchased my Proxmox VE Community Subscription, "uploaded" the license key using the Subscription view in the control panel but the check fails due to connection timeout.
The server is a dedicated server hosted by Hetzner.
Do you have any idea if the issue comes from them and/or can you suggest me where to check to understand where is the issue?

Thanks,
Pietro

It was the firewall but: which port is needed to be open to verify the license?
Should it be kept open or can I close everything again?
Where is this requirement documented?

443, the key will be checked several times during the months.
