Hello, here is the problem: System is Win10, P3Dv4, EFB 1.6.9. Display unit on the networked computer does not connect (ok on the sim computer) . Port numbers on Provider and Display are the same (I tried different numbers). Provider data folder is on a network drive, all drive/folder sharings and permissions seem to be ok. Simconnect clients 10.0.60905.0, 10.0.61242.0, 10.0.61259.0 are installed ... but the DisplayUnit does not connect. What am I doing wrong? Regard
