Hey @nesl1, welcome to the community.

There are a few reasons you cannot connect to your system.

Our support team created a great article to help users to get the system up and running again that I would recommend for you to look into: https://support.sonos.com/topic/connection-issues

I hope that will help resolve the issue, but if not, please provide some details. It can be anything that might have changed since you last connected to the system, such as a new router, a new phone, or a power outage.
