Hi, I just downloaded v15 yesterday and did a new install on Windows Server 2012 R2. Installation was successful and I used 3CX's FQDN and opened the required ports in the firewall. I can access the web gui from internet. First time I logged in I'm presented with the initial setup. All was well until the last page when I need to submit the registration. All fields were filled and I put in the free license key I was emailed. However I got the following error: License Activation Failed license_error.HttpsError I couldn't find anyone else having this issue. Any ideas?
