That looks like you have some other web server running. You can check to see if something has a port open and or see if apache or nginx is running.

That looks like you have a theme that has an error. You might do a

 ./launcher start app

To restart the server (which won’t work if something else is on port 443) and see about removing themes and then adding them back after the upgrade.
