Hi,

Getting the following error

FMOD OS Net Listen Cannot listen for connection, port 9264 is currently in use.

This seems to happen after I’ve launched the game from within the editor a couple of times. Once this error displays, the in-editor game launch will freeze.

Nothing else is on 9264. If you need a log, please let me know how to go about providing one.

Thanks!

Unity 2020.2.1f1  
Fmod Integration 2.01.07

We haven’t been able to reproduce this issue here, yet, but we’re continuuing to test. You can upload a log to us at [https://www.fmod.com/profile#uploads](https://www.fmod.com/profile#uploads).

Just to clarify, does the error message appear in FMOD Studio, or in Unity?

How do I go about creating a log file?

FMOD Studio automatically generates log files as it runs. On Windows, these files can be found in C:\Users\username\AppData\Local\FMOD Studio. On MacOS, they can be found in ~/Library/Application Support/FMOD Studio.

Information on how to obtain log files from Unity can be found in the [Unity documentation](https://docs.unity3d.com/2019.3/Documentation/Manual/LogFiles.html).
