Get the following error when installing our product on a client's new server running Server 2008 R2 without internet access.

Using Advanced Installer 13.5 and Thwarte code signing certificate.
Install works fine on our test server 2008 r2 enviroment but it is a virtual machine and not possible to turn off internet on it since remote desktop to it. Could possibly block the port that it uses to verify the cert but not sure on the port.
I tried installing on a Win10 machine with no internet access and it worked but it might be because I installed the installer on this machine before or the certs ncluded by default on win 10 being newer?
