Can't activate license key

[New3CXUser]

Hi everyone !

I am quite new to 3CX, and I would like to try it but i can't activate the licence key, when I push the "Next" buttton i have this error message :

Unable to connect with 3CX License server. Check your network and try again.

Can someone help me please ? Do I have to open a specific port ?

Thanks !

Hello @New3CXUser

Your PBX should be able to communicate with activation.3cx.com
Make sure you can resolve that correctly and that you do not have any deep packet inspection enabled on the firewall
