I'm attempting to link my railway site to an external domain via DNS (I am new to this so could easily have made an obvious mistake).

I have not set a fixed IP, just in case relevant.

I've set up on Port8080 (maybe need to leave blank?) and told by railway the DNS to add on my 3rd party are "Type - CNAME / Name - @ / Value - a url on railway, not mine"

- in my 3rd party app, i believe i need to enter that with CNAME / www / then the url

- i have also set up forwarding for www.site.co.uk to go to just site.co.uk

BUT on clicking site.co.uk i get "The connection for this site is not secure

smarterbuys-banking.co.uk sent an invalid response."

On clicking www.site.co.uk
