Unable to access server remotely (sometimes)

[CraigR4 3]

I have my media stored on my QNAP server and have set up port forwarding correctly.

I use no.ip  DUC v4.1.1 to ensure my external IP address is up to date, but sometimes I am unable to access my server remotely (or my BT home hub internally).

If I reboot the home hub, it seems to resolve itself, but don't understand why emby is the only app that seems t be affected.  I can still access my server through my QNAP cloud and Plex (sorry).

I realise this is likely to be an issue with the BT home Hub, but wondered if anyone else had encountered/resolved it ?

What happens if you via QNAP restarts Emby server ?

Can you then access it ?

I think Emby uses a Schedule to check external ip addresses, but a restart should force the check.

In any case I use smart plug to restart a hanging router, if you still have access.

That will not work if internet is down, unless you setup some sort of failover network.
