Real Debrid dropping out every 5 mins onn CinemaHD

Anyone else having problems with CinemaHD whilst streaming movies using Real Debrid.
Cinema brings up all the Real debrid links from 4K down to 720p and all seem to work OK the ones I have tried.
The issue is that RD drops out approx every 5 mins while trying to watch a movie. sending you back to the list of links.
It is annoying and I wonder if anyone has any suggestions. the only way to watch the movie with min disruption is to save to history every 5 mins so you do not have to FF to the lost position every time it drops out.
Things done already:-
subscription is up to date
I have deleted the Firestick RD account and re installed. this has stopped it happening for a short period.
I watch Cinema through my VPN and has worked fine up to now, only change is I have changed from IPvanish to NordVpn
Running orig CinemaHD not the relaunched version

Running out of ideas now.

I would really think about ditching cinema, there are way better options available.
Firstly try stremio once setup it just runs flawlessly.
Stremio guide.
You can also try kodi, there is many guides on troypoint.
