It looks as though you’re trying to publish on a different port. Are you trying to put Discourse behind a reverse proxy?

I would revert the expose statement for now and try accessing over 80 first if so.

If you’re just trying to install discourse on something other than 80/443 for direct access please note that this won’t work and isn’t supported.
