Bridge won’t connect

Hi everyone. I just got the Ring system, and so far it’s been great. My app was able to easily find the doorbell 2 and the backyard floodlight cam. Then I hit a snag. The bridge just won’t connect. It’s plugged in and the blue light does flash. But when the app asks to join the network, it searches and fails. I’ve tried restarting my router and changing my WiFi from the 5G to the regular connection. Nothing. Any advice?
