License Key

Hello
I have a question about the free evaluation license. I used it once, and now 90 days have passed, I applied for a new license, but it does not work.
When I use License Key I face this error
(Unable to connect to the remote server)

Hi,

it doesn’t sounds like the error message I expect if a known Cyber Security topic is the reason, nevertheless I would recommend to check out this post:

Could you please post a screenshot of the error message? Is there any more information inside, like error numbers or so?
