The Projetex 3D Server uses TCP ports 212 and 47111.

Please make sure these ports are opened and accessible on the computer where the Projetex 3D Server is installed.

You can check whether these ports are opened using the following commands on your server computer:

netstat -an | find ":212"

netstat -an | find ":47111"

Run these commands in the "cmd" prompt. 

At least one connection (for each port) should be in the LISTENING state. 

If there is no such connection, please contact your System Admininstrator or Internet Service Provider with this issue.
