@Goldenkracker Thank you for the follow up! While there may have not been any changes you have made to your network settings, it’s possible that you may have gotten an update to your router or modem from your ISP that put up restrictions again that may have not been in place before. I only mention this as I have ran into this myself, so I just wanted to make sure we checked that out as well.
At this point, since the device is still not activating the Live View, it would be best to reach out to our support team here for more advanced troubleshooting. Since you have a fair RSSI value, have ensured no network changes have been made, have reset the device and even readded it, we would need our team to take a deeper look into this and see what could be causing the Live View from never loading. Please let me know how this goes, as your resolution may help out other neighbors that come to this thread!
