Running Alfresco Community Edition v5.2.0 on Linux - i know this question was asked several times before, but the final solution - if LibreOffice is running properly - does not work for me. So: i fixed everything to run LibreOffice headless (installed Nightly 6.1.x, because due to a bug in LibreOffice it actually wasn't able to run headless without x on a server [the defunct .soffice.bin problem]), but still creating previews with LibreOffice does not work, the preview-image appears broken and the webpreview does not load at all. If i open the URL of the Image directly i get the following error:
06230053 Wrapped Exception (with status template): 06230063 Failed to execute script 'classpath*:alfresco/templates/webscripts/org/alfresco/repository/thumbnail/thumbnail.get.js': connection failed: socket,host=localhost,port=8100,tcpNoDelay=1; com.sun.star.lang.IllegalArgumentException
Quoting the "--accept=..." argument in "ctl.sh" as proposed as solution in some other answers regarding this problem doesn't fix anything for me (i am also not sure, why this should work anyway - isn't ctl.sh executed as part of alfresco startup-process, only? There's also no tcpNoDelay option in my ctl.sh - so the preview-rendering-subsystem must be executing soffice.bin somewhere else - but i am unable to dig this up).
Any ideas how to solve this problem?
