How to share a vagrant machine with https - vagrant

Question

I have a working vagrant VM I want to Share. In my Vagrantfile I have:
config.vm.network "forwarded_port", guest: 80, host: 8080
config.vm.network "private_network", ip: "192.168.1.15"
config.vm.network "forwarded_port", guest: 443, host: 443
in the virtual host I have
<VirtualHost *:443>
...
ServerAlias *.vagrantshare.com
....
</Virtualhost>
not sure about the first line but it was there already
I share the machine with
vagrant share --https 443
this is the output:
==> default: Detecting network information for machine...
default: Local machine address: 127.0.0.1
default:
default: Note: With the local address (127.0.0.1), Vagrant Share can only
default: share any ports you have forwarded. Assign an IP or address to your
default: machine to expose all TCP ports. Consult the documentation
default: for your provider ('virtualbox') for more information.
default:
default: Local HTTP port: 8080
default: Local HTTPS port: 443
default: Port: 2222
default: Port: 443
default: Port: 8080

default: Share will be at: towering-badger-9312
==> default: Your Vagrant Share is running! Name: towering-badger-9312
==> default: URL: http://towering-badger-9312.vagrantshare.com
==> default:
==> default: You're sharing your Vagrant machine in "restricted" mode. This
==> default: means that only the ports listed above will be accessible by
==> default: other users (either via the web URL or using `vagrant connect`).
I can see it in vagrant cloud but I got an error while trying to access it via https:
towering-badger-9312.vagrantshare.com is currently unable to handle this request.
HTTP ERROR 500
not any other useful message in the console, any idea how to debug this?
thanks

Answer 1

Replace this line
config.vm.network "forwarded_port", guest: 443, host: 443
with i.e.
config.vm.network "forwarded_port", guest: 443, host: 8443
first, because forwarded_port is for accessing from your host and second, you should not be able to bind to port 443 on host.
Also
vagrant share --https 443
is redundant (docs):
HTTPS (SSL)
Vagrant Share can also expose an SSL port that can be accessed over
SSL. For example, instead of accessing http://foo.vagrantshare.com, it
could be accessed at https://foo.vagrantshare.com.
vagrant share by default looks for any SSL traffic on port 443 in your
development environment. If it cannot find any, then SSL is disabled
by default.
so
vagrant share
should suffice (assuming there's no other issue).
