Hi! This is because you need to proxy the websocket protocol. You may want to read up on it in [1] and [2]. [2] being the reference point and [1] being an introductory blog post with a simple app example to try out if your config is all right.

Hello

I'm trying to deploy openstack services behind the NGINX reverse proxy

NGINX is in charge of SSL termination, and communicates with openstack services unencrypted

When I set "html5proxy_base_url" option in [spice] section of nova.conf file to "http://my-domain-name:6082/spice_auto.html",

spice console in web UI works(by manually typing http://my-domain-name:6082/spice_auto.html in browser address tab), but chrome refuses to load spice console because its http

If I change html5proxy_base_url to " https://my-domain-name:6082/spice_auto.html",

spice console page(spice_auto.html) loads in chrome, but console itself is blank

And I get following errors from chrome developer tools console:

...

...

disconnect spice_auto.html?toke…8-3a537f56f5b0):144

<< disconnect spice_auto.html?toke…8-3a537f56f5b0):157

ERROR: Error: Unexpected protocol mismatch.

Seems like spice-html5 uses different protocol based on "html5proxy_base_url" option in /etc/nova/nova.conf (whether its https:// or http://)

How can I deploy nova-spiceproxy behind the NGINX reverse proxy, while NGINX is acting as SSL termination point?

Thanks
