This is a new issue on an existing setup that has been working fine for years. 3 cameras are wired, 3 are wifi connected. After rebooting my router last week I can now only view the 3 wired cameras (outside of the network) on my mobile app. The 3 wife cameras won't appear. However, If I reboot the wifi cameras, they show up for a few minutes on the app and then lose connection. All 6 cameras use no-ip as the ddns provider for remote viewing and they have all worked fine up to this point and all 6 cameras show up fine internally (within network). Port forwarding has been checked and all ip's and ports are still the same. I am baffled.
