I have installed a OpenStack with RDO at a Google Cloud Plataform Machine, with Google Compute Engine. I have configured my VM so I was able to access OpenStack endpoints from my machine. But I cannot access them anymore. If I hit, for example, http://[external_ip]/dashboard, I get Not Found - The requested URL /dashboard was not found on this server.

It is weird because I can't access them not even at VM console, it happens the same there:

curl -v [internal_ip]/dashboard -> 302, as expected;

curl -v [external_ip]/dashboard -> 404, but should also be 302.

I do not remeber changing anything, so I don't know why external IP is not working at all. Am I doing something wrong?
