When Right-Clicking on a VSM and try to deploy the model to a VSE server, Deploy/Redeploy to [email protected] Option is disabled in the Workstation.
If VSE server is not running, Deploy/Redeploy to [email protected] Option will be disabled / grayed out.
If there is a firewall issue this will cause the same issue.
Start the VSE Server, this will enable the Deploy/Redeploy to [email protected] option in the Workstation and should be able to deploy the VSM.
If the VSE is running and still getting the issue, it is probably due to a firewall. Make sure all DevTest ports are open to not only send but receive data.
