SPICE connection not working, HTTP proxy connection failed

[headcase]

I'm receiving an error when attempting to connect to a SPICE enabled machine. I'm not sure how to debug this issue, the port appears to be open and connectable, but connections from remote-viewer fails. Here is the debug information that is spit out when I try to connect.

xxx@xxx~$ remote-viewer --verbose --debug download

The spice file provided by Proxmox looks like this

[virt-viewer]

I do have an nginx proxy sitting in front of the management interface for Proxmox, if that would have some affect, although the SPICE port is just exposed.

What operating system is on your client? What is 'pveversion -v' on your host?

Did you follow the steps described in the wiki or have you edited something manually?
