This can be caused by the use of incompatible 3rd party liveries.
Please try the following:
- Ensure your Fenix A320 is installed into the default path of: C:\Program Files\FenixSim A320
- Check that the Fenix.exe application is running and not blocked by an antivirus. Maybe try a restart of the app if it is.
- Try a restart of the Flight by closing the Fenix.exe, pressing ESC then Restart and checking that the Fenix.exe application has started once loaded into the flight.
We have also noticed some liveries can break the connection. Please try using the default Fenix livery to troubleshoot.
If the above does not work, please try the following:
Please go here:
C:\Users<user_name>\AppData\Roaming\Microsoft Flight Simulator\
Open SimConnect.xml and change the setting of all MaxClients entries to 128 and save. Then launch and see if the issue is resolved.
