Nuki Opener not finding Bridge

Just wondering if anyone has had similar experience or any advice as to the problem I’m having with connecting an opener to my holiday let. We have a smart lock which works fine and when connecting the opener, and going through the set up process it gets to the Actuate door opener and after a minute comes up saying ‘to configure the opener you have to be connected via Bluetooth or Nuki bridge’. Hit retry and you just can’t get past that point. This is despite the Bridge being present and showing all connected.

I’ve see other issues similar to mine but no replies that help.
