Hello!

This is a know "error" in MacOs Monterey and beyond.

MacOs runs an Airplay server that uses port 5000.

You have two solutions:

1. Change the port used in your bun application
2. Disable the Airplay server in your system preferences that runs on port 5000.

@AmFlint Thank you, sorry, i didn't noticed or searched for it. Used port 4400 and it worked
