BT Vision shows ipc6023 error after 5 minutes even with latest firmware update

Hi,

I know this has been discussed before however has anyone found a solution to fix the BT Vision/youview ipc6023 error for internet channels(All)?

I have updated firmware - v1.0.2.36 - and am still having issues.

igmp is disabled (unticked) and bt tv is ticked

In my situation, it works for 5-6 minutes everytime, before displaying ipc6023.  When I switch channels to another internet channel and back again it comes on for another 5-6 minutes before displaying ipc6023 again.  All aerial freeview channels work as they should.

Also ipc6023 after 5-6 minutes when I use the VLC stream for the bt 399 test page on my laptop.

It worked previously with the home hub 3 only, so I assume the nighthawk (or its settings) is the issue.

My setup is simply openreach modem > nighthawk router > bt/humax youview box > onkyo av receiver > tv

Thanks for any help in advance and I hope there is a solution for anyone else having the same issue.
