Hey @Weeks149. Since you've already reset your devices and re-setup them up, have you also attempted to reboot your router? Sometimes it can be related to the RSSI for your device as well. Please check out this Community post here to learn more about RSSI and see if this fits with your concern. If you can, please attach a screenshot of your device health page so the rest of the Community can help further! Please make sure to block out any personal device info such as the MAC ID that you would not like shared publicly.
I was having the same problem with my doorbell camera when trying Live View with both my Cell phone and Computers but when I tried very early yesterday morning it worked and has continued to work as of this date and time.
