This error usually occurs when a user has multiple instances of Voyager running on their machine.
Possible issues causing the error could be:
1. Two VoyagerServer.exe processes running simultaneously. To resolve this,
Note: When running Voyager as a process, ensure that there's only one VoyagerServer process running i.e. the Windows Task Manager>> Processes only has one VoyagerServer.exe process listed.
2. Voyager was installed as a service, but also accidentally started as Voyager server using the Voyager icon in the Windows Start Menu. To resolve this,
Note: If Voyager was configured as a service during installation, Voyager Service gets started automatically when installation's finished. Users don't need to click on any icons to run Voyager as service; it is started and stopped using the Windows Services Panel only.
