Thanks Colin, yes it does, but I followed some tutorials and made the problem is even worse, wiping sd card with fresh backup image and will give you the results when setup again.
My question hasn't been answered and maybe the whole problem, do I append the proxy code [andrei-tatar] gave me to nginx.conf or overwrite or comment out something? I have never tried a reverse proxy before and the first time I have touched nginx.
Sorry I can't help with the fundamental problem, I just knew where to find the error log so hoped that might help. I haven't used nginx in that way. I setup a VPN on one of my Pis for remote access which I found fairly simple and works well, for me anyway.

Probably there is a missing } or something similar in the file.
Can you post your config file if you can't see the problem. Put a line with three backticks on before and after it here so that the forum doesn't mess up the formatting.
Sorry for lack of response, life has been busy. This post was intended for people having trouble using default ngrok with node-red as I was, I still don't understand why it was only me that was having trouble. Default ngrok may work just fine for you
I strongly recommend using user/password option at all times if you haven't already set up node-red-admin, having devices naked on the web is never a good idea, no matter how short you imagine the time, there are a terrifying number of bots just looking for open systems out there.
