Hello All, I am just getting started with meltano in my local and trying to get

meltano ui

working. For some reason its failing with this error and not able to figure out a solution.

MainThread|gunicorn.error] [ERROR] Connection in use: ('0.0.0.0', 5000)

Hey @jethin_abraham! By any chance are you in a mac and recently upgraded the OS? That error means the port the UI uses by default is already in use by a different application. https://meltano.com/docs/contributor-guide.html#getting-setup

Potential MacOS port conflicts

On recent versions of MacOS (Monterey/12.0 and up) an AirPlay related service may be bound to port 5000. In that scenario you may want to specify an alternate bind to port to start the service on a port other than 5000. If you would like to continue using that port, please consult this Apple Developers Forum article to how to reset port 5000.

Thank you.. changing port did the trick .
