I have Tomcat 8.5 running on my Mac OS Sierra, and whenever I configure Connector port="443" is says that port 443 is in use.
When I do
nmap -p 443 localhost
in terminal it returns:
PORT STATE SERVICE
443/tcp closed https
and
lsof -i:443
returns
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

I was trying to open 443 port by following this guide: https://gauravsohoni.wordpress.com/2015/04/14/mac-osx-open-port/ , but it did not help.
