[tor-relays] Ports 443 and 80 are open, but 443 not Tor reachable

Thank you very much for your suggestion which pointed me in the right direction. It was my router that was grabbing port 443. A very helpful page on the Draytek website explains how to forward TCP Port 443 - for SSL VPN models. I had asked Virgin Media about running Tor and no objection was raised. I was told they do not block any ports.. Again, many thanks.
