fails to work with spice-html5

[ReubenM]

spice-html5 + xSpice work together to provide a web based spice client similar to how noVNC + xVNC provide a web based VNC client.

The connection does not get passed through using the module. It does however pass through when using the standalone websockify.

[tg123]

please provide some error log if you can i am going to setup the xSpice and check your problem

[ReubenM]

The X server logs don't show anything because they never detect a connection.

Nginx logs contain stuff like this:

[debug] 24208#0: *7 websockify : found SEC_WEBSOCKET_KEY : U8mvZT8iQbY8RA9RuWvI7Q==
[error] 24208#0: *7 connect() failed (111: Connection refused) while connecting to upstream, client: 172.16.0.189, server: , request: "GET / HTTP/1.1", upstream: "websockify://127.0.0.1:5901", host: "172.16.0.189:5959"
[info] 24208#0: *7 client 172.16.0.189 closed keepalive connection

[tg123]

Connection refused means your nginx is not allow to connect the upstream 127.0.0.1:5901

please telnet 127.0.0.1 5901 on the same machine to see if you can connect from nginx to upstream

[ReubenM]

I must have copied and pasted from he wrong location in the logs. I removed all logs and ran it again to make sure I have the right content. The error should have been about timing out rather than connection refused.

Here's the complete uncut error log:

Also, I checked and telnet can connect to the 5901 port. Using both the LAN IP address, and localhost IP address.

Here's the related portion from nginx.conf

        server {
                listen 8080;
                root /var/www/spice-html5;

                location / {
                        index spice.html;
                }
        }

        server {
                listen 5959;

                location / {
                        websockify_pass 127.0.0.1:5901;
                }
        }

No longer times out, but console output from spice.js on the browser reads "Error: Unexpected protocol mismatch."

No connections are shown in the X11 logs.
