Three stick up cameras, one not showing feed

I recently set up three stick up cameras around my house and within 24 hours, the camera closest to our modem will not show a live feed or respond to a siren test. I’ve gone through the help tips in the app, rebooted the camera, removed from WiFi, charged and changed batteries, and it still will not connect. The two others cameras work just fine and are further from my modem. When checking the device health, it says it is connected to WiFi and has decent signal strength. The blue light on the camera itself turns on when there is motion, but no feed.
