I Will create a bug report, but what versión are you installing in your cloudservers ? One downloaded from StandardInstall or versión downloaded by CN.
If versión published in StandardInstall is not the same as the one in HW cloud servers, please can you specify where to download that versión.
Manual provide us the steps to setup Webclient, If We cannot make it work, it doesn´t matter what versión HW is using. Webclient is a feature offered by SERP that anyone, anyplace, in anyserver must be able to setup easy.
Did you test in your computer with manual download and manual install? Is there any way to have a demo versión in you cloud server so I can do test with your working versión ?
Best Regards
