Thanks for the info. The client browser opens properly with
"--authKey", "${secret}" removed. <br><span class="">

${port} should be there otherwise "pvpython
pv_web_visualizer.py" is not issued. <br>
<br>
Thanks! <br>

<div>Hi All</div>
<div><br>
</div>
<div>I tried to install paraview web with apache as the
front end and followed the information on <a href="http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#%21/guide/ubuntu_14_04" target="_blank">http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/ubuntu_14_04</a></div>

<div>The web browser can open the index.html and when I
tried to open localhost:8080/apps/pipeline, the client
browser issues a warning "authentication error" and
pipeline page closed automatically. The backend opens
a "pvpython pv_web_visualizer.py --port ${PORT}
--data-dir ${data_dir}", but failed at </div>
<div>"--authKey ${secret}"</div>
