Hey there, @Jarkko! A Chime reset is best performed by holding the setup button for at least 20 seconds. Once a reset is successful another setup will need to be completed in the Ring app. As you mentioned there are lights showing on your Chime, this is a great sign that it is powered and attempting to operate.
Please attempt to setup the Chime in your Ring app, while also ensuring your Chime is close to your wifi router, for best results. If this concern persists, and setup is not successful, please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
