Hik-Connect Can no longer see NVR via Hik-Connect App after firmware update

[Wisetech]

Hi
I have updated firmware on
NVR DS-7716NI-I4 to lates NVR version 4.0 firmware version V4.21.004 built 190509.
Since new version I can’t see NVR via Hik-Connect app
Network settings as below

I can access NVR via web browser via Local IP

Platform access is enable but shows offline I have restarted Router and NVR few times still no luck

I tried via port forwarding from router as well

I can see NVR on the app via local network

Please advise if new version NVR 4.0 doesn’t support Hik-Connect app via serial numbers?

I'm not sure what's happened there.
The IP addresses that you have shared look fine.
In Network Settings are your DNS addresses set?

Maybe try this slightly newer firmware version:
New I series NVR firmware - 4.21.008
