License Activation Problem Vm, 15.5.15502,

[CIESLAK]

I block on an installation with the validation of the licenses on Web page, whereas during the installation, the update is done well. I use Mozilla to fill in the license number. I also tested activation in SSH, and I have the same result.

With Mozilla, a message in red indicates that the server is not accessible. However, my Vm has access to the Web, and all IP 3CX URLs are accessible:

• IP 151.80.125.88 <> https://activation.3cx.com
• IP 151.80.125.73 <> http://downloads.3cx.com

If I run a tcpdump between my Vm and the activation server, I have the certificate exchange between my Vm and the activation server in TLSV1 for the server hello, and the hello done. By cons I have a fatal alert that tells me that the certificate is Unknow CA on both servers 151.80.125.88 & 151.80.125.73, and after HTTP / 1.1 200 ok. Everything should roll but still the message of impossibility to join the server. Can you guide me?
