No access through Wifi to DVR with K2 app

Hi, I'm already a long time a happy daily and 4 season user of my K2 camera system on my Honda Super Blackbird. :-)

Since the update of the app I don't have access to my camerafiles and configuration settings anymore. The app always mentioned that there's no wifi connection with my camera. But I have wifi connection to the camera with my smartphone and can see all the files via the internetbrowser on my phone on IP 192.168.1.254 So there is a perfect connection between the 2 devices.

I have also 30 minutes ago updated the firmware 0.64 of the camera, made a new connection, reinstalled the app, but all without any results. Problem stay's the same. :-(

I saw there are very short movieclips made, so the update is ok, just need to make the old settings back like before.

Can you suggest any tips or hint. Am I doing something wrong or is there a bug somewere? Thx in advance for any help ;-)

Kind regards Jelle
