FMOD Unity 2.03.12 Unity 2022.3.62f2 I keep getting the follow warning in the console, what is it about and how to fix it? ```ini [FMOD] FMOD_OS_Net_Listen : Cannot listen for connections, port 9264 is currently in use. UnityEngine.Debug:LogWarning (object)FMODUnity.RuntimeUtils:DebugLogWarning (string) (at Assets/Plugins/FMOD/src/RuntimeUtils.cs:580)FMODUnity.RuntimeManager:DEBUG_CALLBACK (FMOD.DEBUG_FLAGS,intptr,int,intptr,intptr) (at Assets/Plugins/FMOD/src/RuntimeManager.cs:108) ``` But it seems the project can still detect incoming change to bank file builds ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/f/fec198e427b491e85c71a6e4a917728805725cb8.png) ---

Hi, Your Unity instance is trying to connect to [FMOD Studio | Glossary - Live Update](https://fmod.com/docs/2.03/studio/glossary.html#live-update). [FMOD Studio | Editing During Live Update](https://fmod.com/docs/2.03/studio/editing-during-live-update.html) Live update can be disabled in the platform settings: [Unity Integration | Settings - Live Update](https://fmod.com/docs/2.03/unity/settings.html#live-update), which will stop the Unity integration trying to connect to your FMOD Studio Instance. If you want to connect to the studio instance I would suggest following these steps: [Issue with Live Connecting in 2.02.15 - #2 by Leah\_FMOD](https://qa.fmod.com/t/issue-with-live-connecting-in-2-02-15/20505/2) . Or restarting you PC should help too. Bank refresher just checks for changes to the bank files on disk and is not related to the warning. Hope this helps ---

@Connor_FMOD Thanks for your response. I have turned off the Live Update and the warning is gone. However, I don’t remember ever changing this setting before, the warning just popped up one day – but I may be wrong. ---

Live update is enabled in the Unity Editor by default. There are a couple of reasons why the port may no longer be free, different software or having multiple FMOD Studio instances open could cause issues too. ---

Appreciate the update. With FMOD Studio opened and live update enabled in FMOD Studio, Unity is able to connect to it. ---
