If you have a network license but are unable to connect to it when starting the software there are a range of possible obstacles and solutions.

First, double-check the actual error. If you see one of the errors mentioned above with a network license, you will still need to resolve those issues as mentioned above first.

After that, there are a few things to check, both on the local client machine and on the remote license server.

You could start by opening Vision4D on the computer that runs the network license server to see if the license is running correctly. However, most network licenses are configured on systems where only the license server is installed, not the Vision4D application. On this kind of machine you should start by opening a web browser and going to HTTP://localhost:1947 to access the Sentinel Admin Control Center. 

Clicking the Sentinel Keys tab on the left will show you all the licenses currently running on the machine and give you a lot more information about the status of these licenses. 

Keys with vendor ID 66215 are licenses for arivis products. If you do not see a license with that vendor ID then no arivis license is running on this machine. The checks mentioned above regarding hard and soft keys are also relevant here.

If you see a license for that vendor ID, you can check what type of key this is. Network licenses running on USB dongles will show up with a red USB key icon to match the physical key on which the license is configured. If you see a USB dongle icon, but it is not red then it may be that you do not have the right type of key for network licenses and you should open a support ticket using the link at the top of this page. Soft licenses will be indicated by a Certificate icon in the Configuration column.

Clicking on the Features button next to the arivis license will show you if the license is valid. If the key is expired, please contact sales or support for more info.

Assuming everything on the Sentinel Keys page is OK, the most likely problem is going to be a network port configuration. Make sure your port is configured to enable communication on port 1947 for TCP/IP as mentioned above.

You should also check that no exceptions exist for access from clients under the Configuration tab.

If the network configurations and the license is OK on the server side, you should then double-check the settings on the client side.

First, as with the server, make sure that port 1947 is open for TCP/IP on the machine as mentioned above.  If you need to find where it is blocked, run a trace route from the client to the server and inform your IT of the address it stops at.

Next, open the Sentinel Admin Control Center by opening your web browser and going to http://localhost:1947. In the Access to Remote License Managers, you can enter the IP address of the license server to force the system to check that specific address. this is especially useful if using a VPN.  Please note, when clicking submit on the IP address field, you may only see a very brief flash indicating it has accepted the entry.  To verify, click on a different menu and click back on the Access to Remote License Managers tab to see that the IP Address is still present.

If you are unable. to open the Sentinel Admin Control Center from your browser this usually indicates either that the sentinel drivers are not installed correctly or that the port is blocked. Check with your IT to re-install the driver with administrator privileges if necessary. 

If all this fails, please contact arivis technical support who can try and diagnose any issues.
