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
