Amcrest Issues with camera &

[SpecialE]

Have a simple 2 set up camera... everythings been fine until the weekly sunday reboot.
My camera (Amcrest 2K 3MP) keeps saying "cannot connect to host login" when viewing it from my Amcrest NV2104E

Ive done the rebooting and the re-adding the camera. On device search the camera is shown but with a red circle instead of green. If i use the amcrest app and add the camera to my phone, i can see the live feed (however only if im suing my own WIFI, other sources and i dont have a feed.)

anyone have any ideas? the system and the camera was bought in July.
