Tvheadend

narrowed this down - it only occurs when reverse proxying the UI.

if i go to ip:9981 the full UI shows.

reverse proxy is setup as below:

ProxyPass /tv http://IPADDR:9981/tv retry=0
ProxyPassReverse /tv http://IPADDR:9981/tv

I know this isnt an apache forum - but if anyone has a rev proxy setup can they share? the above worked fine until recently

Add websocket proxy config to apache. The last tvh webui uses websocket instead HTTP for the instant connection to the server.

would that be:

ws://IPADDR:9981/tv

?

The config should be similar to http one.. TVH use 'ws://IPADDR:9981/comet/ws' only at the moment (without the proxy prefix).

n/m - that got it. thanks!


ProxyPass /tv ws://IPADDRESS:9981/tv
ProxyPassReverse /tv ws://IPADDRESS:9981/tv


Can you show the entire vhost config?

I enabled proxy_wstunnel in apache and changed the config from http:// to ws:// but am getting error 500. Apache complains that there is no handler...

<Location /tvheadend>
       ProxyPass ws://tvheadend.domain.local:9981/tvheadend
       ProxyPassReverse ws://tvheadend.domain.local:9981/tvheadend
    </Location>

Faced the issue. This works for me now:

ProxyPass /tvh/comet/ws ws://localhost:9981/tvh/comet/ws
ProxyPassReverse /tvh/comet/ws ws://localhost:9981/tvh/comet/ws
ProxyPass /tvh http://localhost:9981/tvh
ProxyPassReverse /tvh http://localhost:9981/tvh

So I only pass /comet/ws to ws://

What is advantage of proxy vs port redirect?

That worked a charm for me too - only difference is my base URL is tv rather than tvh and im proxying to a different IP rather than locally:

ProxyPass /tv/comet/ws ws://192.168.0.2:9981/tv/comet/
ProxyPassReverse /tv/comet/ws ws://192.168.0.2:9981/tv/comet/ws
ProxyPass /tv http://192.168.0.2:9981/tv
ProxyPassReverse /tv http://192.168.0.2:9981/tv@

This worked!

Wasn't obvious to me that the websocket proxy should be added specifically for comet.

@Saen acro, I'm proxying multiple service through a dedicated web proxy in the DMZ using SSL. This makes maintenance easier and tightens security.

Time and processor loosing.
Good firewall rules on cheap router make same easier and faster.
Port change, access list limit easy pizi.
VPN... make miracles

FYI, the way you're using websockets will not work in Safari/WebKit, because they read the standard as explicitly refusing HTTP Authentication. I've raised a bug on this.

For Nginx the following man helped me:
http://nginx.org/en/docs/http/websocket.html

EPG was the only tab and I had the following error in logs:

[  ERROR] http: 172.17.0.1: HTTP/1.0 GET /path/tvheadend/comet/ws -- 415

Working Nginx conf:

location /path/tvheadend {
    proxy_pass http://127.0.0.1:9981;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

Run params:

/usr/bin/tvheadend -C -c /config --noacl --http_root /path/tvheadend

How ...

Base on the settings from ngix.

For apache is need more than

the Proxy and the reverse

And based on this is information need some rewrite
https://stackoverflow.com/questions/22002744/how-to-set-up-an-apache-proxy-for-meteor-sockjs-and-websocket

So after that my reverse proxy is ok

Settings

  ProxyPass /tvheadend http://localhost:9981/tvheadend
  ProxyPassReverse /tvheadend http://localhost:9981/tvheadend
<Location /tvheadend/comet/ws>
        RewriteEngine on
        RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
        RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
        RewriteRule .* ws://localhost:9981/tvheadend/comet/ws [P]
 </Location>

I use --http_root /tvheadend/
