Thanks for your analysis. I run the client and server near every day, so i cant comprehend why there is a gap in the logs. maybe i picked up an old file?
and i never use the ingame pause mode. I will check all your suggestions an report back.
in my last flight over the weekend i recognize following behavior: When i start the server an client before msfs or any other tool like navigrapf fsuipc volanta is started aivlasoft connects correctly and works as expected. If i start firtst msfs (like i do it since beginning) after then all tools, aivlasoft didnt get connected correct.
thanks for your support until now.
