ZoneMinder 1.29 / Fedora 23 Server - Live Streaming not working via proxy server.

[boomerling]

1. Live streaming works from intranet.
2. Live streaming works via VPN.
3. Live streaming is not working when using a pound reverse proxy on an edgerouter appliance.

Note: this feature was working in 1.28 with the modification to use relative URLs instead of absolute URLs. I see that this earlier recommendation is now included in the 1.29 build. What else can I be missing?


4. I have disabled the SSL requirement in the zoneminder.conf (@ /etc/httpd/conf.d) since SSL certs has been applied with the pound proxy configuration.

I honestly do not know where else to check configuration-wise to determine why live streaming is not working via reverse proxy. I am just getting web.php socket errors when I look at the log file.

2016-02-09 10:55:25.494564 web_php 12709 ERR socket_sendto( /var/lib/zoneminder/sock/zms-394981s.sock ) failed: No such file or directory /usr/share/zoneminder/www/includes/functions.php 2371

Any assistance would be greatly appreciated.

Again, this was working seamlessly prior to the 1.29 upgrade.

You need to look in the Apache logs on both the ZoneMinder server and the server doing the reverse proxy-ing and see what they are saying.

I am a novice, so my troubleshooting skills are lackluster:

IP: 146.23.66.6 is my external IP
IP: 192.168.1.1 is the EdgeRouter running pound proxy.
{deleted}: my domain scrubbed from output.

The proxy server is indicating that the service is not available (e503 no service); the sockets are not being created in the location being referenced in the apache log.

This means there is no TCPIP route to the host machine. That is either a network error or the firewall on the zoneminder server is blocking the request.
Also double check your Proxy directive. Make sure you've got the right hostname or ip address entered.

The socket won't be created because the http GET request to zms, which triggers creation of the socket, is not getting through.

Resolved.

1. Firewall was not the issue. Turned off firewall and issue still remained.
2. HTTPS on or off not the issue. Reverted zoneminder.conf to force HTTPS usage.
3. The issue was with the pound reverse proxy configuration. While the configuration worked for 1.28, it would not work for 1.29. Modified the configuration as follows:

Thanks again for your assistance...really like the updates that come with 1.29. Memory utilization down 40% on my server.

Update. Live view is somewhat working. I have 10 cameras. 1-2 shows; 3-4 no display; 5-6 shows; 7-8 no display; 9-10 shows.

Every other couple of cameras do not display their live feed. Will look into this further.

Resolved - believe it or not it, I deleted my Safari browser cache and the issue disappeared. The fix or resolution is the the update to the pound proxy configurations.
