Hi Stephen, Can you tell us a bit more about your setup? Are you accessing this from the public side? Do you have all the needed ports added as a port forward rule? 5080 is not enough on its own. If you are accessing it from the private side then nslookup needs to be the private address (depending on your firewall of course) - just need to know a bit more about how you are set up to troubleshoot this with you.
Also did you use the guides on the wiki to set the reverse proxy up? Either Debian or Ubuntu guides have a section at the end on reverse proxy setup. I'm accessing the system from the public side. My intention is not to use the usuall openmeetings ports, but to "forward" everything through port 80. As far as I understood the two postings, there are two things that have to be configured: 1. two proxy configurations in the webserver config. 2. change the ports in red5/webapps/openmeetings/config.xml to port 80, too: <rtmphostlocal>rtmpt.xxxx.de</rtmphostlocal> <rtmpTunnelport>80</rtmpTunnelport> <rtmpport>80</rtmpport> <red5httpport>80<red5httpport> I will have a look at the guides, maybe there is a difference to the two postings.
