System coupling not working at all
 

Hi,

System coupling is not working at all with me. Giving me every time this error:
"(DP 0) System coupling run completed with errors. Fluent (Solution 1) reported: Exception encountered when the coupling service requested ChartableData->GetRootLevelName: Communication socket unexpectedly disconnected. Please do not save the project if you would like to recover to the last saved state."

I tried the suggested solution before for changing the license preferences but it did not work.

I created a simple fluid solid interface, to test it, but also it did not work.
Please help

Here is the shared link of the simple project I created.
