Whiteboard onerror SWF!! canvas.mediaerrortimeout over Apache proxy

[Noel Lopez]

Hello everyone - I was wondering if someone can help me with this error.

This error comes up when I move a file to the whiteboard. For example a PDF file.

onerror SWF!! canvas.mediaerrortimeout exceeded for http://myserver.com:5080/openmeetings/DownloadHandler?fileName=f6cdaacc06a41b0076121a14aeaf5842%2Eswf&moduleName=videoconf1&parentPath=%2Ff6cdaacc06a41b0076121a14aeaf5842%2F&room_id=files&sid=85ac8314d481c8b76a54f600aefa9234

My current setup is an Ubuntu server running 10.10. Latest Java.

Basically the Red5 server is running internally on port 5080 for http and 1935 for the rtmp.

If I access the server with the internal IP address 192.168.x.x:5080/openmeetings

I do not get this error.

I only get this error when I use the Apache proxy.

I configured Apache to proxy port 5080 and open the firewall to port 1935

my proxy setting on Apache are

ProxyPass / http://localhost:5080

ProxyPassReverse / http://localhost:5080

ProxyPass /open http://localhost:8088/open

ProxyPassReverse /open http://localhost:8088/open

ProxyPass /send http://localhost:8088/send

ProxyPassReverse /send http://localhost:8088/send

ProxyPass /idle http://localhost:8088/idle

ProxyPassReverse /idle http://localhost:8088/idle

ProxyPass /close http://localhost:8088/close

ProxyPassReverse /close http://localhost:8088/close

ProxyPass /fcs http://localhost:8088/fcs

ProxyPassReverse /fcs http://localhost:8088/fcs

I haven't change anything within the Red5 configurations.

Thanks in advance.

Hello Noel,

my installation works great with these lines in my apache config:

    ProxyRequests Off
    ProxyPass / http://localhost:5080/
    ProxyPassReverse / http://localhost:5080/

i had never problems during uploads of pdf or office documents

I hope this helps  =)

Hey Noel,

have you firmly checked your firewall rules?
maybe there is a problem...

[Noel Lopez]

Yes, I have Port 80, 443 and 1935 Open on Both TCP and UDP for testing.

Thank you

[Noel Lopez]

Hi Sascha - Have you change anything on the Red5 side? 

did you changed port on the config files?

[seba....@gmail.com]

yes:

red5.properties
and
config.xml

And do not forget to clear your browser cache after changing the config.xml

sorry,

that would be the usual way to do it.
If you are using mod_proxy you need only to change the clientside ports,
so the one in config.xml.

Hello Noel,

i changed NOTHING at the openmeetings configs =)

mod_proxy works without changes in red5 - still using 5080 and 1935
maybe you should recheck your apache configs - it seems, you use mod_proxy for other things (port 8080 stuff)

on my machine, there are other VirtualHosts which uses mod_proxy in several ways - have you tried to set up an own virtualhost for openmeetings?
so its possible to exclude other config problems & you get an own access & error log. maybe you find any answers at the logs.
for me, the problems seems not to be on openmeetings-side - but maybe i am wrong ^^

just for completion - my apache2 modulelist (debian 5.0.8)

command (as root): apache2ctl -t -D DUMP_MODULES

result:

of course: dont forget the cache! =)

[Sascha Xander]

and another thing:

netstat -tunpl shows me the following:

tcp        0      0 0.0.0.0:1935            0.0.0.0:*               LISTEN      12183/java     
tcp        0      0 0.0.0.0:9999            0.0.0.0:*               LISTEN      12183/java

tcp        0      0 0.0.0.0:8443            0.0.0.0:*               LISTEN      12183/java    

maybe can sebastian tell us, which of these ports are responsible for the whiteboard drag&drop task...

lots of thoughts... sorry for spamming =)

[Noel Lopez]

I will check my settings. am I to assume that the only port open in your firewall is port 80?

thanks for the help
