<div class="moz-cite-prefix">Hi Sebastien, <br>
<br>
OK, I finally upgrade to Ubuntu 14.04 and apache 2.4! however, I
still have some issue. again I see the render window pop up in the
background, in the browser I have the ParaView web logo and
spinning wheel, now after a few seconds a dialog: Session did not
start before timeout expired. Check session logs.<br>
<br>
I cranked up the log verbosity in apache. attached everything.
Any idea what the problem is? how to get more info? paraview has
an error, how does that get reported?<br>
<br>
Thanks<br>
Burlen<br>

<div>You may need to build Apache yourself on that distribution.
The one that have all the fix and is supposed to work is
2.4.7+.</div>

<div>Hi Sebastien,<br>
<br>
this is for a public deployment but I am testing in the
browser while it locally logged into the system. This
server is running ubuntu 11.04, apache 2.2.22. I hope
that this isn't a roadblock.I can't easily upgrade.<br>
<br>
your instructions for 14.04 went off OK but in 2 spots I
had to find a work around:<br>
1) proxy_wstunnel had to be installed manually, this
went without a hitch and it loaded up without error<br>
2) in the apache config I had to comment #Require all
granted as that wasn't valid in 2.2<br>
<br>
the session id was in the proxy.txt file and had the
port number 9100 which I see elsewhere in the logs, so
that looks OK.<br>
<br>
I'm attaching the launcher config.<br>
<br>
the apache config is pasted below.<br>

Making an attempt to install ParaView web. I

Seems that the problem potentially relates
to web sockets. How can I get further info
