Based on your description that it can be accessed on 'localhost' and not
externally would lead me to initially believe that it's only bound to
127.0.0.1 and not the external ip.

What does this command show?

netstat -ano  | findstr LIST | findstr :443

It should show something like:
 TCP    0.0.0.0:443           0.0.0.0:0              LISTENING       9488

or
TCP xxx.xxx.xxx.xxx:443           0.0.0.0:0              LISTENING
9488

where the xxx.xxx.xxx.xxx is the external ip but should not be:

TCP    127.0.0.1:443           0.0.0.0:0              LISTENING       9488
