I have set up the DVR server using a RPI per the instructions. It starts up fine and works for about an hour. Then I can no longer connect to the unit, either thru dvr-server.local:8089, or the apps on IOS. If I reboot the RPI then it will work again for about an hour.
The drive is a 1tb SSD. For a test I installed the server on my laptop and using the same drive I had no problems. But the laptop won't always be connected so that is not a permanent solution for me.
Any ideas on what is going on and what I can do to fix the problem?
