I also guess the problem related to Kepserver settings. I have changed the hosts file (enable the line "127.0.0.1 localhost" ) and switched the Windows Firewall off. Thanks!
We just tested it on Win 10 without issue but i faced the issue with Win server.
Thanks to all for your replies!
We will try to find the reason for this behavior and get back to you.
Hi Seb, I downloaded latest trial version on the official website. Just I checked the version of "Thingworx Industrial Connectivity", it is 8.3.65. My OS is Windows Server 2012, installed on Virtual Machine.
