Unable to set License-ID - What to todo - Exitkode 35

[Serverhus]

Hi,

I've tried to install Magicspam and everything looks good.
However, when i get to entering the Licensekey inside WHM, the webpage stand at "Waiting for...", and then, after X minoutes, it displays this error:

Error on update: [Fatal error executing remote url fetch. Exit code: [35]]

So I'm stuck. Any ideas?

Hello Serverhus

This appears to be a connectivity problem with your MagicSpam server
not been able to verify the license key, the server needs to connect to
TCP destination on port 443, please check on your firewall settings.

Please let us know if this helps, or if you have any more questions.
