ok redux (had posted about this issue then thought i did had forgotten to change the DNS IP address as well as the static IP address so that was causing the issue but i had also just changed the time (which requires a reboot) and the IP address was also lost
so to bring everyone up to speed :)
have a RPI3b+ that i had marked has having a bad HDMI port and a few USB cameras - and what does everyone need but more cameras so i thought motioneyeOS :)
first boot allows web access
any change requiring a reboot the RPI loses the IP address
any ideas what might be causing this issue?
thanks
