With ORPort 443 Tor could not confirm the port was reachable even though it was wide open to online port checkers and nmap -sT -O localhost shows ports 22/tcp, 80/tcp, 443/tcp to be open.
Where are you running this from? You said a Raspberry Pi; Is this on a home/residential network? If so, my first inclination is that your ISP is blocking incoming connections on certain ports. I know this is common in my area with port 25, 80, and 443 to prevent customers from running servers.
A netstat/nmap on localhost will confirm that Tor is listening on the port, but wont confirm the outside world can access it. You said you used "online port checkers" - double check this. Try running a simple http server on port 443 (you don't need to setup ssl necessarily, just run it at http://1.2.3.4:443) and seeing if you can connect from your mobile phone or something.
I believe you when you said you checked, but sometimes online port checkers can be iffy and even your ISP might be doing some weird conditional filtering. I run my Tor relays on 443 and it worked without issue.
And yet torstatus monitors show many relays displaying ports ORPOrt 443 and DirPort 80 running on Linux.
Yesterday I swapped the ports and within a moment ORPort 80 was confirmed and server descriptor published. DirPort 443 fails to confirm it is reachable.
So what is it about port 443 on my little RP 2 that Tor dislikes?
